Hello!

Last night in our garden (northwest Germany) together with the Mirid bug Orthops campestris, which measures about 4-5 mm.

there are many genera with that 3 stripes on thorax, and some other genera with that stripes on abdomen and the spots on "knees" and tarsus, so just as a starting point, female Cricotopus, it will "appearantly" fit, at least, but donīt trust, Iīm unable to find the synonims from the faune de france to todayīs species and palaeartic keys are old too and very expensive : ( good luck (and nice pic, they are difficult to shot for me)

Many thanks! Now that you write it, I remember some earlier Chironomids, which were identified here as Cricotopus sp.. Same size, same yellow colour, similar stripes on thorax, but not so distinctive one on abdomen.

sorry, Iīm learning, looking at Faune de France keys for Cricotopus there are different patterns of b/w bands on abdomen and C. trifasciatus confused me; the book species has not the white line among the last 2 black terguites as the one you posted (yes has a white line between the first 2 terguites, 2 more black terguites and the last one), Iīstill canīt dischart other genera, but trying this (be careful, nearctic) itīs reasonable, at least : (

the second one has a bigger dark spot than yours
I hope any expert says something : |

Thanks, paqui!

By the way a correction: the Mirid bug is not Orthops campestris, but Lygocoris (Neolygus) viridis (ID by R. Dietze).

They are not Potthastia. I think they are Orthocladiinae.
