OK, for this week’s photograph we have something slightly different. A tiny little beast which although scary looking is harmless to us, but scary indeed if you’re a caterpillar as it is a predator and parasite.
This is an Ichneumon Fly. They parasitise caterpillars and other creepy-crawlies by laying their eggs in them for their larvae to eat from the inside.
These are the four best shots of a tiny ichneumon which wandered into the house. I suspect it if being a member of the Braconidae, possibly Apanteles glomeratus; almost certainly one of the Ichneumonidae. Its head and body about the size of a British black ant (so around 4-5mm) with the antennae and ovipositor each roughly the same length as the body. Its legs were definitely reddish. It liked walking about (it was quick too) and then suddenly flew off into oblivion.
Ichneumon Fly?
