Moving flower pots under the bench in the greenhouse, I came across a black hunting wasp* with conspicuous white dots halfway along its antennae. There also appeared to be a white dot at the rear of its thorax. It’s been a mild day and it was even warmer in the greenhouse, even so I was surprised by how active it was. It didn’t appear to be just running for cover after I’d removed the plant pots, it appeared to be actively hunting on the surface of the damp soil. Its antennae were exploring all the time, moving independently of each other.
It was a little over a centimetre, about half an inch long, perhaps a little longer including the long antennae.
* It’s an Ichneumon – a relative of bees, wasps and ants – Ichneumon suspiciosus, a common species throughout the British Isles. Seeing it from above, I’d noticed a brownish tinge on its wings which was, in fact a broad red or orange band on its abdomen. The species also has pale spots to the rear, which I didn’t notice as it scuttled along.
