Tachina lurida on the wing
Had a nice record from Tristan Bantock on the 17th – a Tachina lurida, seen on Parkland Walk near Crouch Hill tube station. They look superficially like the slightly earlier Tachina ursina but they are slightly less hairy and they lack a white band on the front of tergite 5.
We’re also getting plenty of reports of Gymnocheta viridis on the wing in the UK – usually seen sunning themselves on fence posts and tree trunks.
