How to write a good blog...

Erm.....
I just wanted to begin a bog entry with that word! I've been reading about the 'correct' way of writing a blog and apparently, you should always get right to the point of the blog and always be decisive, never hesitant.
I've always fought against people telling me the right way to do things, after all it's all subjective? It's my blog? One person's right way might not suit the next?
Oh bugger! Now I've broken the other rule about not getting to the point!
Best crack on then, whilst you're still there..

You'll now be rolling around laughing at my pre-amble no doubt (if not then humour me) and so whilst I'm tickling your funny-bone, I couldn't resist a quick photo when I passed this sheep when out walking t'other day...



What I've always wondered about sheep is:why is there only one word to describe singular and plural? I'm trying to think of another British animal that has the same for both?

The weather is still unfavourable in the main but we've been lucky enough to get a few hours of sunshine here and there, and that has been the time when I've been out with the camera and I've been able to find a few interesting things. The early moths are a welcome sight and this golden winged beauty was a nice find. Good numbers of these are appearing around oak trees now-it's a species that I usually see around the first week of April. But as with the cuckoo, that was also later this year and the damselflies which I've yet to find, it seems we may be a little behind here.

An even better find at the same location was the moth pictured below;this moth is the same species but the more uncommon form 'fastuosella' that has these wonderful dark blue, metallic blotches on its wings.

My ladybird sightings have consisted of almost exclusively 7-spots but I did see this 24-spot recently. These are one of our smaller ladybirds at around 3-4mm and are vegetarians. I've also read that it's unusual because it seldom has wings. It has a fine covering of hairs that makes it appear duller than most too.

Last year I photographed one of these that had just emerged and had yet to gain its spots: all ladybirds emerge without spots and then acquire them in the first few hours.

Whilst checking Jack-by-the-hedge for brassica bugs, I found this little sawfly-I'm not sure of species on this one but possibly Dolerus species? This one is a natural light shot.


--------------------------------------------------------------------------

Here's another of those 'can you identify' type pictures to ponder...

Any ideas?

Here's another big clue-does this help at all?


If you're still unsure as to what the top photograph is, then take a look at these profile shots...


Yes, these are Alderfly eggs. I visited local lakes a couple of days ago to look for early damselflies (non to be seen) and spotted these eggs in huge numbers. They were on most of the reeds beside the lakes and each batch contained, I guess close to one thousand ova. They must be expecting a high rate of predation once the larvae emerge and drop into the water. I know that they can take up to two years to mature and so I guess numbers will deplete during that time, otherwise we'd be overrun with these insects.

 Amazing how regimented they are

Like many aquatic insects, the adult life of alderflies is short – just a week or two from the time they emerge in late April to the end of June. By contrast the larvae live underwater for around 2 years, or occasionally three.
 The dark brown adult alderflies, which carry their wings folded in the shape of a tent over their backs, emerge from ponds, rivers and lakes in spring and early summer to mate and lay their eggs.




This last photo shows the alderfly actually in the process of egg-laying.

Even though my bug-hunting days have been few and far between through April, there is so much to see on the good days now that for once I have quite a bit more that I could share with you. However, nobody wants to spend too long reading a blog and so what I think I'll do is call it a day and then perhaps add another entry in the next few days. Call it a second instalment-it consists of photographs that were all taken over the same period and so will supplement this entry nicely. 

Until the next time then...

Return of the frost...

There is a quote that uses the analogy of painting styles to describe the seasons, I can't remember it word perfect but it's along the lines of, winter being an etching, spring a watercolour, summer an oil painting but autumn a mosaic of them all.

Well, that was the premise behind these shots.I purposely took them out of focus to give an impressionistic vision of Autumn. Rubbish? Probably, but it pleased me so indulge me?






Autumn is just beginning to come alive though and we've been lucky enough to have quite a few clear, sunny days. The two shots above were taken directly behind our house using the little Lumix camera that I've started to carry with me more often now that the colder weather is here.The colours are a bit over saturated but I kinda don't mind too much.


It's also been possible to get a good daytime view of the moon lately.


Whilst I don't seem to have had a great deal of spare time to go bug-hunting recently, it's also true that there are considerably fewer around to see anyhow.
On fine days I still spot the occasional butterfly and as usual there are caterpillars around if you look in the right places.



These two pictures are examples of recent finds that illustrate perfectly how the variation in form, size and colour can make caterpillar/larvae identification tricky. The top one of the two above probably would be most people's idea of a caterpillar when in fact it isn't a caterpillar at all. Whereas, the second photo possibly isn't how you would expect a caterpillar to look and yet this one actually is a small copper butterfly caterpillar.
In case you're wondering...the top one is a sawfly larva.

One creature that will be around throughout this winter however bad the weather gets is the springtail or collembola. These hardy little things can sometimes be seen crawling around on the fresh snow or ice.If you do fancy looking for these yourself, I ought to warn you that the one I've photographed here is one of the largest of the species but even this one is only around 5mm or so.

A Springtail

We have already had a few overnight frosts in this corner of Kent; not hard frosts but enough to turn the grass white and to have to scrape the car windscreen. There's little doubt that the harsh temperatures will have already been responsible for the demise of a good number of our insects. Dragonflies are one species that are not safe in the cold.

When I spotted something moving on a small piece of wood laying in a crop field whilst out walking recently, it shocked me to find that it was actually the common darter dragonfly shown above. It was soaking up the last of the day's sunshine and was fairly slow to the point where I was able to get a few shots before it moved off. A nice sighting so late in the year and especially so following the frosts.

A couple of days later I was walking the dog on one of my regular routes when I thought I'd check some rhododendron bushes beside a local pond to see if there was any sign of bug life. I'd seen the spectacular rhododendron hoppers there earlier in the year but couldn't imagine that these tiny things would have survived the recent frosts; once again I was proved wrong when not only did I find one but counted at least a dozen on different bushes.

Rhododendron leafhoppers


Speaking of hoppers, whilst walking at the edge of a ploughed field I heard the unmistakable sound of a grasshopper but couldn't actually seen one. I did spot it eventually even though it was well camouflaged. I'm unsure of just which particular grasshopper this is but here's the photo anyway...





Squashbugs are mainly confined to the south of the country and of the 10 species, only two are classified as common. The one that I see most often is Coreus marginatus, the 'Dock Bug'. They feed mainly on fruits and seeds and also possess stink glands and it's for this reason they are sometimes also called 'Stinkbugs'

Coreus marginatus

These bugs can when threatened emit a foul smelling odour from the stink gland that is meant to deter any would be predators.

A closer look at the stink gland

The last photograph in this blog entry is of a little weevil that I found running around on the edge of a cattle trough. It's usually to be found on dock plants, hence it's name of 'rumix'.

Apion frumentarium (Red rumix weevil)

That's about all for now but I'll be back with another update soon. This strange year for insects isn't over yet and there are still some nice finds to be had if the weather continues to be kind.

Until the next time then...
