This one really is Rhogogaster viridis. Nice unicolorous green pterostigma, dark dorsal markings along abdomen, and much larger than the Cytisogaster chambersi I had a few weeks ago.
Black scutellum and thorax, yellow band on tergite 4, sides of tergite 5 and extreme apex of tergite 6.
And I've got this one to Tenthredo brevicornis
Yellow stripe on the first tergite constricted laterally, yellow bands on the hind edges of tergites 4-6 which broaden laterally, and black basal antennal segments.
Also from the same trip, a new bug for me that I saw sitting right on the edge of an oak leaf at head-height and netted ....
Phylus melanocephalus - which funnily enough has a black head, and lives on oak
Good to see another Rutpela maculata - not that it would play ball for a photo
And several Brown China-marks around the pond - not one I recall seeing dayflying before
This week has been a lot cooler, and a bit damper though we've not in any way had a deluge. The moth trap has not been out since Monday night either, but after a busy few days I'd like to get out and do something. Before the lockdown I bought a pond-dipping net so maybe time to think about using that - I guess a cool overcast day won't make much of a difference.
Meanwhile, nothing makes rave better than a bit of bassoon ....
