Style,grace and class.....Not!

Phew! Finally made it back here to update. Life gets in the way sometimes...so unfair!

At the closing of my last update I hinted that I'd been lucky enough to witness another 'first' regards invertebrates moulting. This time it was, well let me show you a photograph, maybe you will recognise the individual?

A bit unfair I suppose because it is kinda contorted here as it struggles to free itself from the exoskeleton, but it is actually a speckled bush cricket...








I guess I watched for around 15 minutes and it still wasn't completely free of its old 'skin'...so vulnerable for such a long time.


Back in June whilst visiting Blean Woods near Canterbury, I spotted what I thought were emperor moth eggs-the only doubt in my mind came from the fact that they were on grass and I know that bramble is the main food-plant for emperors...



I took a few home to observe and meantime had another look at emperor eggs to see if these were a match...


I found these on the internet and they look a good match to me.

The only thing to do was to wait for the caterpillars to emerge, offer them both grass and bramble and see which they preferred?

It was quite a wait! Like a pregnant father I paced up and down for the next 15 days-slightly melodramatic? Possibly, but I had started to think that nothing was ever going to happen. But then...


Hmmm...looking very like emperor caterpillars aside from being a tad more hairy, or possibly just that the hairs seem a bit long? Once they'd demolished the shells, I added fresh bramble and grass and waited...

I guess you'd call the result inconclusive! Some headed for the grass, others the bramble and each tucked into their chosen meal. Perhaps the first moult would prove conclusive?


Well certainly with that orange banding starting to appear, they are looking less emperor-like, but what could they be?

They continued to feed and grow well and by the time of their last moult I finally realised that what I had were not emperor moth caterpillars at all but fox moth.

A new one on me, I hadn't seen either the moth or larvae before but they are impressive caterpillars, being about equal in proportion, but slightly slimmer, than the emperors...



The amount of butterflies and caterpillars I have been sighting has definitely increased dramatically of late, after what has been another poor year to date, at least locally. On a wander around farmland the other day, I saw these small tortoiseshell caterpillars...


By the way, as they approach pupating, caterpillars increase their intake quite markedly and here's a little video of one of my poplar hawk moth cats doing just that. This is real time..it's also a bit shaky as it was hand-held by...my shaky hand...

Just a reminder that this won't show in the e.mailed version of my blog

Now as often happens, I have been preoccupied with leafhoppers of late, just because I found an interesting one whilst looking for something else and that started me searching for more...and more...and...well, you get the picture? And if you haven't got the picture yet-here it is...


I couldn't offer an identity for this tiny nymph but, it's kind of cute, especially so when you consider the next photo...


I had to get the macro lens on this one as they are so small, I suppose it was about 3mm or so but once I had,I could see the huge hole in its abdomen, or perhaps more accurately, where its abdomen had been?

 Gruesome enough, but then...I was sure I could see movement inside! I waited a while and checked again-holy smoke! (apologies for all the exclamation marks) There was something and like a scene from Alien, it began to emerge (Don't use another exclamation mark John....don't...don't...just don't!.........Bugger!) What crawled out of the hopper was this...



What is it? No idea would be the closest I could get at present. It sort of looks like a dayglo hoverfly larva but, as 80's songstress Toyah once sang...'It's a mystery' for now at least.

Vying for the title of brightest addition to this blog update is this next little hopper nymph...



At least I can i.d. this one though; it's a rhododendron hopper. They turn this bright yellow colour at about the third moult, having previously been off white...



The adult is quite colourful too...



Erm...this is a bit out of sync should have added it when I was talking about parasites but anyhow; is this perhaps another, or even the same type of parasite still inside a hopper?



I may be at risk of repeating myself here but this kind of thing is what keeps me so interested and enthralled by nature. This year is the first time I have found/seen anything like this and each year brings something new. As somebody once said...'No man can be truly called an entomologist, the subject is too vast', or something similar to those words and the point is that there will always be a surprise around the corner as long as I keep looking.


Now...what this entry needs to really complete it with style, grace and class is a picture of some caterpillar poo...




You'll thank me one day you know? The next time you're at a dinner party and the conversation turns to invertebrate feces, you will be without doubt the only guest who can offer to identify caterpillar poo. Just to ensure that should that fact not be sufficient for folks to think you're some kind of oracle, you could quickly add that the poop of the alder moth (for that's what this is) is....groovy! 


Until the next time...

A neglected Kentish orchard...

Immediately behind our house is an area of land that was once a thriving apple orchard, but has now been neglected for a number of years.
As nature reclaims the orchard, the habitat is gradually improving for insects and bugs. Until such time as the land is needed it makes for a great hunting ground, right on my doorstep.



I thought that I'd dedicate this blog entry entirely to creatures that I've found in this area in the past few days. Armed with my pith helmet and machete I ventured into the jungle...




This sawfly larva seems to be around in good numbers and I did find quite a few in a fairly small area of the old orchard.
I'm never sure on identity with these sawflies and so won't even attempt a guess here but I can show you another example of the same species-this one has some little hitch-hikers in the form of mites...



The next find was this very cool hopper. I think this one might be Aphrodes bifasciatus but once again not completely sure, as it's a variable species-I think it's safe to say that it's Aphrodes species though.


This species belongs to the cicadellidae family of leafhoppers.They feed by sucking plant sap from grass, shrubs or trees. This one was under 5mm in length.
My plant knowledge is pretty bad but I'm confident that this hopper is on Ribwort Plantain, there, that's left myself open to correction!
    
A couple more views



Each time I walk this particular area my footsteps are accompanied by the sound of crickets/grasshoppers calling but for some reason I've not got around to trying to photograph any-until now that is...

Roesel's Bush-cricket
I caught this one in full sun and it was quite lively, staying in one spot just long enough for a snap. It is Roesel's Bush-cricket (Metrioptera roeselii) a cricket that is separated from the similar Bog-Bush cricket by the pale yellow, or green border that edges the pronotum.
The song consists of long bursts of sound, said to resemble a dentist's drill.

I'd have to say that this little grasshopper pictured above was something of a star find for me. Not because it is anything special by way of rarity or form but just that I was amazed by the facial markings that appeared when I put the macro lens on it. I've said it many times now but this is what makes macro photography so special for me-the unexpected detail revealed through the lens.

It'd be obvious to choose the mottled grasshopper as an identity for this one but in truth, I have no idea which species it is! It was only around 10-15mm and found in an area of long grass beside water.

Edit: Since posting this image I've been told by a flickr contact that it's actually a cricket rather than grasshopper and could even be the same species as the one in the first picture (Thanks Neil) and so probably best to ignore what I've written about a possible identity!


The water  is actually a small pond and the pond is home to a host of insects and bugs. The dragonflies that I've seen in reasonable numbers previously, have been hit badly by our awful weather this year and numbers are way below what I would expect.

There have been some though as this empty larval skin shows. I spotted this prehistoric looking thing whilst searching for damselflies at the water's edge.





If the dragonfly skin looks like a monster to you then here's something I found that demonstrates the other extreme. The world must look like a pretty big place to this little turtle bug I spotted...

A Turtle Bug- Podops inuncta




Leptopterna dolabrata



Leptopterna dolobrata is a common species of large grass bug (Miridae) and the males are always fully-winged but females are usually partly-winged, as in the photo of a female above.


I said that the grasshopper/cricket was a star find for me and it was, but I was equally excited by another stellar spot-this time a beetle. Not just any old beetle though, oh, no!


This stunning creature is a beetle from the Buprestidae family. Known as jewel beetles for obvious reasons, sometimes also as metallic wood-boring beetles. I don't find these too often, I think this may only be the third in all the time I've been bug-hunting and so it was quite a treat.

Butterfly sightings in the old orchard have been limited to mostly meadow brown and ringlet. A few small skippers have begun to appear though and I also spotted a couple of comma's on nettle. I once overheard two gents discussing species and heard one say "Oh no, I don't like skippers, they're not a pretty butterfly" well, firstly to me that sounds a ridiculous statement, and secondly, I don't agree-I think they are very nice and I love the subtle colours.



This fly, pictured above is not the sharpest of images but was taken very early one morning in the orchard. I was trying to get some natural light shots hand-held but the light was poor and even dragging every drop of light I could into the camera, it still required a low shutter speed. It was windy too and has made me decide that before I attempt a similar excursion, I must get a device to hold foliage steady for me.

Anyhow, I wanted to include this one as it's quite an interesting looking fly and has great eye colour.  I think these are marsh flies.



Sometimes you have to look underneath leaves to find insects and bugs and that's how I came to find this strange looking critter. It was underneath a willow leaf.
I have seen something similar to this with ladybirds where the ladybird has been attacked by a parasite-I'm pretty sure that this is an aphid that has suffered a similar fate.

On that final gruesome note, I'll put an end to this update. Quite a lot of finds then for a small area that I didn't really spend much time in. I may add to this at a later date with an update of anything else of interest that turns up.

Until the next time...
