At last the weather relents...

What a change since I last updated the blog-the weather is what I refer to of course. We seem to have left the wet stuff behind in favour of sunshine and warmer temperatures (I hope I don't regret saying that) and it now feels as though spring has been urging winter to retire in favour of new life and has grabbed this opportunity without waiting to see if it was done.

Just today walking locally, I spotted primrose, cuckoo-flower, blackthorn, violet, wood anemone all in flower.
There were lots of brimstone butterflies, a few comma butterflies, as well as peacock and small tortoiseshell.

The pussy willow is coming in to flower now and that is always one of the earliest forms of pollen available to the insects...

Did you spot the butterfly in that picture?



The honey bees have also returned in force and were busy on the crocuses...
(Please be aware that if you only view the e.mailed version, this video won't show, you'll need to click the link at the bottom of the email.)




I spent around three hours at Ashdown Forest last week, I arrived early morning to search for adders but despite a thorough search of several likely areas, found none on the day. There were a few other finds as always and so it wasn't a complete waste of time and maybe I'll try again in a few weeks.

Ashdown Forest


Continuing meanwhile with the tradition of mystery objects...this is from the fence in the garden and I almost overlooked it, thinking it was just another spider 'nest' and who knows, maybe it'll turn out to be exactly that. What particularly interested me though, were all of those tiny orange dots. I can't pick out any detail myself from this one photo but I shall be keeping an eye on it to see what develops. The whole thing is I would guess about 20mm across.

I know for instance that garden spider spiderlings are yellow when juvenile and so maybe orange isn't so strange after all?







You might remember that I mentioned in my last update I had seen my first moth of the year. It had actually flown into the house-well, here's the photograph that I took at the time. I am still not certain of the identity but offer Tortricoes alternella as a possibility. It's only a tentative idea and is really based around that species being one of the earliest to emerge.

There will be somebody who knows for sure, there are far too many for my liking to choose from. I hope to improve my skills though as I get into using the moth trap again through 2014.
In fact, I may well dig it out and set up in the next few days if the weather stays as it is.




Since that find I have discovered another moth. This time on one of my afternoon walks. It was sitting on a fence-post and well camouflaged. It seemed very lethargic and wasn't at all bothered by my taking pictures and was still in exactly the same spot when I passed again sometime later.

I wonder if this one could be an early grey moth. Flying time seems just about right but again, just not sure-to me the markings seem to be less distinctive than I would expect. Whatever it turns out to be, it is nice to see these returning as so many insects are now that the weather is more forgiving.




Now....here's the exciting bit I've been dying to share with you since getting the latest photograph; I said in response to a comment on that amazingly tiny cocoon in my last update that I'd try and add an updated photo here. Well I took another close-up (x5) shot of it just today and there has been a big change as you can see for yourself here...



I'd be interested to hear if anyone has an idea of exactly what may eventually emerge using just the clues in this photo- there are some definite...shapes! But what are they? It has just occurred to me that it may be a parasite?

Finally for now, here's what I think is a wolf spider exhibitinBallooning behaviour (link)..




Until the next time.....

I reveal just how hoverflies keep fit...

I recently had to search through some older images that I have stored on the P.C. for a particular few shots and happened upon a couple of unused photos from earlier in the year.

And so now, they are at last seeing the light of day, as I'll start this update by adding them here...


A Weevil (possibly Stophosoma?)

This large weevil was one that I remember finding in mixed woodland on one of my many walks.
   

The varied carpet beetle (Anthrenus verbasci)
The little beetle pictured above was one that I found in the garden on a white daisy and photographed using a broken lens that had no front glass!



A couple of days ago, my other half said that she'd saved a large beetle that had somehow got itself in an argument with the hoover and lost. Rather than bin it, she had thoughtfully wrapped it in a sheet of kitchen towel, in case I might like to photograph it first?

On unwrapping the towel, I found the beetle you see pictured below-as you can see, it sustained several injuries but I decided it would make an ideal subject for focus stacking....

Lesser Stag Beetle (Dorcus parallelopipedus)
After much consideration, I went for the lesser stag beetle as an identity. Based on the shape of the pronotum and the spine on the tibiae. The other choice would have been a female stag beetle.



I recently posted a photo on flickr of some Sawfly Larvae that were still inside the eggs. It was a shot taken using flash to get as much detail as possible- but I also took a few more natural light photos that give a better overall impression of how they looked in relation to the leaf I found them on...

You can see just how destructive these can be to the host plant, in this case willow. They have only just emerged and yet are demolishing the leaf already.

On the same day I discovered these little things, I also came across some more eggs. This time bug eggs:or at least, bug eggshells, as I think the occupants of these had long gone..



I love those little hinges (or are they catches?) on the eggs. Whichever they are, I am sure they're purpose is to allow an easy exit when the time comes.

I had a second chance to create a focus stack of an insect when I happened upon a lacewing that had somehow managed to fall into a cattle-water trough. At least, I assume it fell in? I certainly didn't push it! In fact, I scooped out several deceased bugs and insects that I may also use for the same purpose.


I photographed these two at x10 mag.




I really will have to try and update the microscope objective from my £1 edition at some stage-it really doesn't have much going for it apart from it is useful to practice with and I suppose, to even get these results is O.K.


Now that most of the summer wild-flowers have finished for this year, it's left to the flea-bane to attract the insects and it does seem to be doing just that. I found a good number of hoverflies on flea-bane in local woodland and even managed to photograph one doing press-ups...




I have included a couple of focus stacked images in this blog entry and this next photo is a good example of how things can go wrong when attempting a hand-held stack in the field.



There's not doubt in my mind that this photo is sharper than a single image would have been, without using a tripod- but there are only two shots that comprise this stack:the third that would have completed it as intended and would have resulted in both wings being in focus, unfortunately was just a little too far out of line to use.

The only other thing to report in this entry is the return of the harvestmen. As you would expect at this time of year, they are emerging in numbers and a variety of shapes, sizes and colours right now...


Dicranopalus ramosus
Until the next time then...

Don't ask stupid questions, unless you want a stupid answer...

`It seems hard to believe but my stats tell me that I've had this blog since November 2010 and in that time I've had close to 10,000 views.

The map below also shows how it now gets read in an ever growing number of countries too, with the green shaded ones being where folks are kind enough to read these missives.

Time then to thank everyone that's either been here from the start or has joined along the way. I'm very grateful that you're there for me, it would all seem a little pointless without you.



Let's crack on with the latest update then...

A couple of things to tie-up from the last entry:in fact, this relates to the previous one as well-the shieldbug nymphs that I've been finding on alder recently.
I've been observing how the nymphs are progressing and today found something rather special.

This was one of those 'Wow' moments that leave you feeling that you have been privileged to be an observer of nature at its most remarkable...



These tiny nymphs were mid-moult when I found them and were struggling to free themselves from their old skins. I was transfixed by this and somehow felt sorry for them, unable to help. It seems such a hazardous thing to have to undergo and to think they have to do it several times before becoming an adult.

I've only been lucky enough to photograph this behaviour once before,and never with this species. It really made my day.



Once the nymphs had fully emerged I could see that underneath there was an adult parent bug. There also seems to be a hawthorn shieldbug nymph looking on.

Hawthorn Shieldbug nymph
Whilst I seem to be compiling quite a nice little set of shieldbugs and their nymphs, here's another to add to the count...

Final instar Woundwort Shieldbug nymph


I hinted in my last update that the rare sawfly larva I'd found wasn't the only uncommon find and I can reveal that my other rarity was...well, have a look at the following photo...



By the way, before I tell the identity of this beetle (if you haven't already guessed that is) why does it always seem to be that when something of real interest like this turns up, you can bet there will only be just one chance of getting a photo and then you'll probably mess-up?

This is not the best shot you'll ever see of this small beetle, but it is the only shot I managed!

Platycis minutus is an 8mm beetle that has a Notable B. status in the U.K.
Looking for all the world like a miniature cardinal beetle but identifiable by amongst other things, the buff antennae ends.


Angle Shades Moth
A couple of moths now:always a pleasure to see these beautifully marked moths. This one was resting on teasel as you can probably tell.

 It has also reminded me of something else that could be considered another unwritten law of macro photography-why is it that just as you settle down to take a photo, in what appears to be total solitude, as soon as your finger hovers over the shutter button, somebody materialises out of the ether and insists on either telling you their live history, or asks the immortal and familiar question..."What are you doing?"- "I'm fishing! What does it look like I'm doing pointing a camera at a moth?" Well that's how the reply goes in my head sometimes, I've not been brave enough to voice it......yet!



The Herald
Clock this one! Scoliopteryx libatrix or The Herald to you and me. This is possibly where I should add the usual bit about clicking on any photo for a larger view, you won't regret it with this stunning insect. If there's a more beautifully marked moth then...well O.K.There are so many moths that chances are there will be, but still, what a beauty and fresh as a daisy.

I seem to be skipping from one species to another here- It's just not cricket is it? But next up is member of the Tettigoniidae family. 



Oh! It is cricket after all! To be precise, a female oak bush-cricket. (I'm never quite sure as to whether I should use caps for species names?) Nothing too remarkable about finding an oak bush cricket on oak of course, a couple of things struck me about this individual though.

The first obvious one was the wing position. I've not seen them being held in this way before. and what about that dodgy antennae too? Then (and now might be an opportune moment to do that 'view larger' thingy again) I noticed something strange about the 'knees'.

I think this may be in the early stages of succumbing to the fungus that takes over its host and encourages it to climb to a high point, in order to spread the wind blown spores over as wide an area as possible?





Enough of the grizzly side of nature-time for an arty spider shot. Taken from quite a distance this one, I liked the way the seeds from the nearby willow herb had settled in the web.


I'm thinking that one more species might well be enough for this update and so I'll leave you with a mollusc...


I was really pleased that this shot turned out as well as it has because the little snail here is only around 5-6mm and I didn't use flash. I haven't been able to put an i.d. to it but I really like it-it reminds me of the coloured glass marbles we used to have as kids.

Until the next time...


Finally,finally! No news to impart regarding the African snail eggs I'm afraid-have given up hope now.


All photos taken with Canon 40d Canon 100mm macro lens and natural light.

A change of county...

I've just returned from a week in Devon and was hoping that this blog entry would be crammed with all the finds from my week in the west country. Sadly, as is becoming the norm this year, expectations eclipsed reality.

Our little terrier 'Herbie' came too and was in seventh heaven, spending most of his time watching the chicken and sheep on the farm where we were staying.



Here he is looking like butter wouldn't melt! Although looking at this photo, it could have been taken anywhere-it was actually at Ham Hill in Somerset where we stopped off en route. Here's a photo of the ham stone that is quarried there, I've messed around with this shot a little and given it a bit of an HDR treatment...


Anyhow, to return to Herbie the terrier (or as a chum likes to call him "Herbie The Love Dog") for a moment. He may look all sweetness and light in the picture: but he brought us back an unwelcome present from Devon, that we didn't discover until we'd been home for 2 days!

This is what I found and only then by accident when stroking him...


Looks horrendous doesn't it. This is 'Ixodes scapularis' a Deer Tick. Judging by the size of its abdomen it had already had quite a good feed too. I've not seen these before but we did spot quite a number of deer closeby and I'm sure that's where he picked this one up. I managed to remove it and despite a thorough search, found no more.

Enough of the gruesome stuff...
Keen to see what was about on the first day of our stay, I scouted round the immediate area but only managed to find this little bee hiding in a flower head of a pot of chives. I think it may have made itself at home there as it was still in the same spot the next morning...


It wasn't that there were no invertebrates at all, but just that I was hoping a change of location and habitat would reward me with some unusual finds.As I'd already witnessed in Kent prior to a change of county, the cantharis species of beetle were everywhere. Even so, it was impossible to resist completely and I have to confess to taking a few shots.


Click on any photo for an even larger view

I think this one pictured above is probably 'Cantharis rustica' but once again, there are several similar species-anyhow, it's a natural light shot taken early one morning.

Monday looked like being a decent day and so we all headed off for Putsborough Sands, close to Croyde and Woolacombe...




After exploring the sands we climbed the hillside above the bay. I was half-hoping that I'd see some fritillary butterflies but the only flutterby I spotted was a speckled wood. I did however find this rather fine chafer beetle...



Aside from the lack of invert finds in Devon, there was still quite a bit happening. For instance,driving through a pine forest on a country lane I spotted a grey squirrel that must have just been hit by a car? It was right in the middle of the opposite side of the road and would be certain to get hit again by the next vehicle.
I reversed back, shoved on the trafficators and jumped out of the car.I managed to encourage it to the verge which it arrived at by wobbling along like it was drunk and then promptly seemed to shake itself and hurtled off into the undergrowth. I assume it must have just been dazed?

Next up was this casualty.....



This little one was sitting in the road close to where we were staying one evening. I'm not even sure of exactly which birdie this will become (if you know, please do tell) but, although we could find no nest nearby, we could hear an adult calling to it just the other side of the hedge bordering the lane.

We decided the best course of action would be to place it close to where we heard the adult, it would at least be safe from traffic there. Even so, it looked a little young to be out of the nest and I wasn't sure if we'd done the right thing.

And so now we're down to a few things that whilst they are still nice finds, are nothing that you wouldn't perhaps expect to see at this time of year...


 An Acorn Weevil


Andrena species of Bee (I think)

My final find of the week couldn't really be included as a holiday-find, as it wasn't until we stopped for a break travelling home, but had already reached Kent that I came across it: even so, these are fabulous beasts and always a real treat to see and photograph.
What am I talking about? The magnificent Green Tiger Beetle! What a stunning creature...







Just look at those powerful jaws-almost antler-like in design. It must be the stuff of nightmares if you happen to be another insect?

That then comprises my total week's worth of bug-hunting. Actually, bug-hunting was secondary to the main purpose of our break. That being to chill for a while and that we did.No noisy neighbours, no traffic noise, no light pollution, plenty to eat and drink and beautiful surroundings-bliss!

More updates soon.

Until the next time then...

Bee-flies at dawn...

The thing about having an interest in invertebrates is that you do need to actively look for the bugs and insects.Even then, sometimes it pays to take a second look at something that at first glance seems uninteresting.

Yesterday, towards the end of the day I was ambling along past a local pond, keeping an eye out for a kingfisher that I've seen there recently, when I noticed that something looked odd about a bud on the branch of a tree as I passed.

Only half-interested, I dismissed it and walked on:but knowing that it's often a closer look that reveals anything that might be there,it nagged at me.
"Go back and have a look" the voice in my head kept saying. "Can't be bothered"    said the other voice! (Don't ask, I have lots of voices in my head all the time-it's rarely quiet in there) And then I found myself stopping and turning back before the second voice had time to complain again.

Anyhow, the internal fighting was all worthwhile on this occasion because had I not taken another look I would not have learned what I now know.
The whole point of this blog is to share these things and so that's what I'd better do....cue first photo!


Bombylius major

And so what you might be thinking is so interesting about this particular photograph?
Well, this is what the 'bud' turned out to be on closer inspection. These bee-flies are a common sight in spring but until now I've  not seen them anywhere other than at flowers nectering, or sunbathing on warm stones etc.

Then there's the additional fact that I've learnt from past experiences that these insects do not usually hang around waiting to have their photograph taken.
I began to wonder then if this one was 'roosting' for the night? A lot of insects will sit out the hours of darkness, motionless until the sun warms/dries them enough to take flight again.I'd not heard of bee-flies doing this and so it would be new information to me if it turned out that I was right.

I reasoned that if it was displaying this behaviour, then an early morning visit would be in order for today with the chances of it being in the same spot pretty high. I took another shot from the other side and made a mental note of just which tree it was on and tied a length of grass around the branch in question to make locating it easier today.



I was hoping that today would start with damp conditions and I'd find the bee-fly covered in dew-I've photographed other insects in this condition and it makes for an interesting shot. However, it was not to be and when I rose at 5.30am it was obvious that there had actually been a frost.
Would my insect be there now? Would it have survived the harsh conditions out in the open as it was? (Stay with me, this is what's called the 'Teaser' in T.V. terms, I'm trying to build the excitement.) Before I would have my answer, there was another little chore that needed to be done:as I strolled towards the area in question it started to dawn on me (do you see what I did there? Dawn on me!...Ahem!) that there could be a lovely sunrise and it looked fairly imminent too.

I'd hardly got the camera set up before an area beyond the trees to the east of me, began to exhibit amazing hues of red, orange and gold that looked like there had been some kind of weird accident in heaven and the angels were bleeding all over the sky. (That's from a confirmed humanist too!).

I couldn't resist...

Just for a moment it was almost overwhelming-the sky was ablaze, there was that early-spring chill in the air, the only sound to be heard was the skylarks  singing overhead and I still had the main event ahead of me.
The sunrise, as beautiful as it was faded in no time at all though and my thoughts returned to the little bee-fly:would it still be there?

I easily located the tree and then correct branch and there it was, success! Not only a treat to see but confirmation of something I'd previously had no idea happened. That's what I love about bug-hunting, there's always something new to learn.The only thing I noticed was that it had moved down the branch a little overnight.
The following few photographs are the ones I shot this morning at around 7am. I tried to make them as interesting and artistic as possible by getting the glow of the sunrise behind the insect, I hope you like them.

 


A male Bee-Fly

I had a hunt around for some further information about this behaviour and managed to put together a few interesting bits of research.
Those who have studied these insects in much more detail than I have found that some of the species will fly along the ground to absorb heat, whilst others fly further up tress to maximise direct heat.

When cold (at night for instance) they will perch vertically, pointing upwards, and they can remain in this position for a week or even longer.
They will then whirr their wings to warm up the flight muscles before take off.
I haven't yet found a definitive answer as to why some are paler with white areas, as this one is. The only plausible answer could be that the ones that emerge early seem to be lighter. I'm not sure I would go along with that myself as I've photographed these lighter coloured ones later in the year.

The adult males exhibit courtship rituals - they hover at height and exhibit territorial behaviour which includes darting at rival males and spinning at females.

That's about it for bee-flies then, I hope you've found it at least half as interesting as I have?

Until the next time then...
