Scientific Name: Agapanthia villosoviridescens.

French Name: L'Agapanthie à pilosité verdâtre or saperde à pilosité verdâtre
5 Key Characters:
Habitat: Damp places where the host plants are present (thistles Cirsium and Carduus spp and hogweeds Heracleum spp). Females bite a hole in the stem of the host plant and deposit an egg. The larvae live inside the stems.
Adult Active Period: May-June-July.
Status: Probably reasonably common but under recorded. The INPN map shows a very patchy distribution, with no records for this area, however we have recorded it in the Aigronne Valley.

Note that the first antennal segment is fat and black with some black hairs, the second is tiny and black, the third is long and dusted pale grey on the bottom three quarters. There are a few black hairs on the black tip of segment three, but not a real brush like tuft. 2 on Marsh Thistle Cirsium palustre by a bief (millstream), Aigronne Valley, May.
