ID possible?Trichrysis cyanea!

Postby pietsje » 23 Jul 2020 18:16

At first I thought Trichrysis cyanea (for me 'the usual (blue) suspect' on my insect hotels). I would like to know if an id is possible. I don't think it's a (Tri)chrysis now after a more closer study of several blue Chrysididae. The head is more square and it's not a match in body type. The abdomen seems less punctuated than I normally see in T. cyanea. But what can it be otherwise than T. cyanea. T. indigotea is very rare in the Netherlands. I have never seen it, it's not likely so the usual suspects are to expect.
Date: today, 23/7
Size: about the same as C. ignita group members on my insect hotels, maybe slightly smaller (about 0,5 mm smaller, I'm not sure).
Location: my garden, The Netherlands southern part on one of my 16 insecthotels.

the colours, especially the darker dorsal area of the metasoma, makes me suspect it's Trichrysis cyanea, the variation in size is very large in this species
