Right in front of Mike the new conservation officer was a Wasp Spider. Of course, arriving late after working on scenarios for the new hut, I noticed it – her – before he did. The species only arrived in Britain about 15 years ago, and it’s certainly spreading.

Anthill ants are supposed to be minute, yellow, and never appear above ground. If so, these weren’t them. While we were digging brambles out of the anthill meadow, as gently as possible because the anthills are said to be one of the best features of the reserve, we couldn’t help disturbing some nesting ants a little. They seem to be black with grey abdomens; and as you can see, they quickly picked up their white cocoons and carried them off to safety. They certainly look as if they’re the owners of the anthills, but since the anthills are supposed to have been made by little yellow ants, perhaps the black-and-grey ones are just enjoying the resulting environment.
