It's that time of year again! A lot of people have been stopping in at the ISW lately, following Google searches for some variation of the phrase "European winter moth." Sure enough, there are moths out and about in Massachusetts, though it is tricky to tell apart the three winter flyers we get: the European winter moth (Operophtera brumata) and the native Bruce spanworm moth (Operophtera bruceata) and fall cankerworm moth (Alsophila pometaria). For your convenience, I present the following links:
- The UMass Extension web page "Identifying and Managing the Life Stages of Winter Moth" - in my opinion the best reference available on the web.
- Previous ISW posts about the winter moths.
