This is a
very large Sawfly, which at first glance, could be easily
mistaken for a Bee. Trichiosoma lucorum is one
of several similarly large Sawflies, which can present
identification difficulties. One of the most likely mix
up species is the rarer Hawthorn Sawfly Trichiosoma
tibiale, which has all dark tibiae, compared to the
lighter tibiae of T. lucorum. The
caterpillar-like larvae feed on Birch. This was one of
three found during May 2009 at Sherwood Forest CP. |
