This wet and cold weather will soon kill off the remainder of our summer insects, but quite a few of our butterflies will survive by hibernating. These include the Brimstone, Comma, Peacock, Small Tortoiseshell and to a lesser extent the Red Admiral (as the majority of these will migrate south back to the continent).
However, the business of finding a suitable spot and settling down for winter is a gradual process. So it is still possible to see a few butterflies on a sunny autumn day, particularly if you scan a good patch of bramble. My current favourites are the pristine, late-emerged specimens of the Comma Polygonia c-album. Basking in the sun with their wings wide-open these raggedy-edged, spiced-orange beauties really do stand out against the dark green leaves. But when, as in the photo below, they have their wings folded, they can be slightly harder to spot.
But that’s a good thing as it is this dark cryptic camouflage and irregular outline that will help keep them safe amongst the dry leaves of winter. Hiding them from the prying eyes of hungry birds and spiders.
Note the characteristic white mark or ‘comma’ on its rear underwing which gives this butterfly its common name. Personally I think it looks more like a squashed ‘v’ but let’s not get into an argument over aurelian typography.
If it survives the winter then it can be one of the first butterflies on the wing next year with sightings as early as January. And I for one will be glad to see it.
Argiope bruennichi – Female
I’m fascinated by insects but spiders give me the willies. I found this strikingly coloured example a couple of weeks back while practicing my grasshopper identification skills in Winchester, Hampshire. It’s a female Wasp Spider Argiope bruennichi which is a species of orb spider.
Initially believed to be a Mediterranean species it has been recorded in small numbers on the south coast since the early 1920s. However, it has started to spread slowly northwards and has recently been found at Lakenheath Fen in Norfolk. Here in Wiltshire it was first recorded in 1999 but is still a relative rarity as it only becomes established where long grass is not regularly managed. To survive wasp spiders need warm summers and mild winters, so with global warming they may become a far more common sight.
Be warned though, although non-poisonous if mishandled she can bite and her fangs are certainly strong enough to pierce human skin.
Pholidoptera griseoaptera – Female
On Saturday I attended a course on Grasshoppers, Crickets and Allied Insects. Allied insects covers groundhoppers, our native cockroaches and the earwigs. So what did I learn? In the UK there appear to be eleven grasshoppers, about fourteen crickets, four true crickets and three groundhoppers, all of which can be identified in the field or from photographs and then keyed out. So for once there isn’t really any need to collect specimens, particularly as most will lose their colour after death anyway. Three of the crickets, the Field Cricket, the Mole Cricket and the fabulously named Wartbiter are protected under the 1981 Wildlife and Countryside Act and so cannot even be handled without a licence from Natural England. Apparently even taking photographs of them is discouraged as this could be interpreted as interference.
