AGAPANTHIA VILLOSOVIRIDESCENS
AGAPANTHIA VILLOSOVIRIDESCENS (There is no common English name for it!)
This specimen is 15mm in length

Mr Robert Brian Angus says:

On 04/08/2016 I observed 6 specimens of this spectacular Longhorn beetle on Hogweed (Heracleum sphondylium), I retained one specimen as a voucher. The grid reference is SE 138124, on the edge of the river adjacent to Mag Dam. The beetle is more active in strong sunlight and does fly readily.

Life History:- The Female beetle bites a groove on the plant’s stem, then lays eggs in the living stems. The larvae feed in the pith channel, later tunnelling towards the stem base for one year. The larvae can move backward and forwards in the pith.

In spring the mature larva pupates at the base of the stem and the adult beetles emerge in the early summer. The adult beetles may striculate loudly when handled.

The beetles may also occur on thistles and the beetle is spreading somewhat.

Finding this beetle means that the meadows are being managed well in respect of wildlife.
