Tenthredinidae is recorded as a pest but there is only few information about it. However, I found an allantus luctifer on an apricot tree, fortunately, I could record its life cycle. Sawfly is not easy to raise. I found a parasitic bee while raising a sawfly but I could not confirm it.

Allantus luctifer's body color is grayish-green color and its head and the edge of its stomach are yellow. It is black around their compound eye. There is a big black dot following their spiracle. When it receives a stimulus, its body rolls up and puts its edge of the stomach up. This insect appears on a ballad singer during fall and stays over the coldest season around there. From May, it gives serious damage to Japanese apricot tree and an apricot tree.
