Some local insects

Earlier in the season, most of the damselflies were blue ones; now they’re all blue-tailed:

This bit of south London is, slightly unexpectedly, a stronghold for the increasingly rare stag beetle. At this time of year you tend to see them flying overhead in the evening; but the weather has been so miserable that I haven’t really been outside much in the evenings. I did see one crawling across the pavement a couple of days ago, though. This, however, is not that species; it’s the more common lesser stag beetle, which is not nearly as big, and even the males don’t have antlers.

This is a hoverfly. Like most hoverflies, it’s a wasp mimic; they nearly all have black and yellow stripes, but they don’t sting. This is more spectacular than most, though; the large size and brownish colour are its attempt to look like a hornet. I think it does quite a good job, although looking at it closely like this it’s obviously a species of fly. We don’t actually have any hornets around here—I’m not sure I’ve ever seen one in the UK, although they do live here—so I don’t know how effective the mimicry is.

And here’s a holly blue. You can see the abdomen curled around on the ivy; presumably it’s laying eggs. It’s lives on the holly and the ivy, which is very Christmassy of it.
