Hello!

:S I feel sure this is not C. vicina! I have tried to go through the key but can't come to a decision. For one, the basicosta does not look pale, not totally black maybe but it is not obvious like I see on viciana nor is it as 'chunky'.

There are 3 pairs of scutellar bristles, the abdomen doesn't look tessellated, the last abdominal segments turn ventrally sharply which I haven't seen in vicina, it doesn't look like it is 'flexing' it's tail end either. The occiput rather than being weakly concave looks convex.

On my wall, near Lincoln UK on 16th January. It was smaller than females I have seen of vicina at ~8mm if I remember correctly.

Help! :D
