Turnip Sawflies
Sun 2010-09-19
Turnip sawflies, Athalia rosae (Hymenoptera Tenthredinidae), mating. This species is easily recognizable by the black 'shoulder pads' on the orange thorax. On the same day as I took the above photo, I also took this one of what I assumed was a dark blue-grey caterpillar, but which I have just realized is probably a larva of Athalia rosae:
This larva was on hedge mustard (Sisymbrium officinale) which is listed at BioImages.org.uk among the possible food plants for the larvae of A. rosae.
Photos taken in Whiteknights Park, Reading University grounds, Reading, UK, on 2010-09-12.
