- Green Sawfly Larva shows the behavior of the larvae burrowing into rotton wood in Juneau, Alaska in early August.
- The following information is from Green Alder Sawfly – A New Invasive By Paul Oester and Dave Shaw, OSU Extension Service
- A native of Europe, North Africa and the Near East, the green alder sawfly (Monsoma pulveratum) (Hymenoptera: Tenthredinidae) was first found in North America in eastern Canada in the early 1990’s, then in Alaska in 2004.
- A pre-pupal stage overwinters and pupation occurs in the spring. After the eggs hatch in the spring, larvae feed on alder leaves through the spring and early summer, then typically drop to the ground to pupate in the soil. In Europe and recently observed in Alaska, these insects have been reported to also burrow into rotten wood to pupate.
- In this video I opened up some rotting wood in order to film them inside.
