Winter Caterpillar
February 24, 2010
Hello Bugman,
I am a follower of your website for several years now. I moved to Canada recently, and have been exploring around Thames River. I came across this caterpillar in the snow in London Ontario.
It was little more than an inch in length. At first I thought it was dead, so I photographed it as it was (first picture). Later when I came back to explore, it had moved almost 3 feet from its location (picture 2) in about 45 minutes, and was on the snow (picture 3)!
This surprised me. I am aware of hibernating caterpillars, but the fact that this fellow was out in the open caught my attention.
Can you help me identify it? Is it a Noctuid caterpillar?
Sincerely,
Ani

Winter Cutworm

Hi Ani,
Last month we received a similar letter from New England, and our faithful reader Karl helped us identify it as a Winter Cutworm, Noctua pronuba, an invasive species that was introduced from Europe.

Hi Daniel,
Thank you so very much for the response! I have been coming across heaps of invasive species in the wild, compared to native species over here, which is very sad!
Thank you again for the information, I really appreciate it!
Keep up the good work!
Sincerely,
Ani

Hi again Ani,
We believe you will find that the spread and proliferation of exotic imported opportunistic species is not limited to Canada, but is a phenomenon that we are seeing worldwide due to human migration. There probably is not a scientist on the planet that will be able to accurately predict the extent of the dire consequences this will have on species diversity, and many endemic species are becoming endangered or extinct at an alarming rate.

Edible!!
This species is edible; therefore anyone wishing to combat an invasive species can use the most natural approach there is!
Also, if anyone’s interested, there’s now an insitutional program to farm edible insect species in Costa Rica; I hope to go check it out in the next six months or so.

Thanks for this information Dave. This will probably be very helpful information for hikers who are lost in the snow and forced to survive in the wilderness.
