   Jeremy Tatum writes:  I haven’t seen many invertebrates during the recent spell of wintry weather, so I have been reduced to photographing a Common Firebrat in my apartment building.

   Mark Wynja writes with sadness of the destruction of one of the best butterfly areas on Vancouver Island.  He writes:

This WAS the best spot to find butterflies in the Nanaimo area. It was also one the best places on Vancouver Island rivaling Mount Cokely and Mount Washington. Known as Km14 of the Nanaimo River Road. About 6 km of this road has had all the trees removed along the north side. For reference, you can see the large boulder in both photos, centered on the before photo and on the far left on the after photo. Heavy equipment has heavily damaged the roadside meadow of spreading dogbane and a nearby wetland has been obliterated.

      On January 12 we posted a photograph, by Sher Falls, of a Thick-headed fly Physocephala burgessi, perched on an Ox-eye Daisy, and we speculated on whether the fly was aware of the crab spider lurking underneath the flower.  This reminded Jeremy Gatten of a very similar photograph that he took a few years ago on Mount Washington, of the same species of fly on the same species of flower, also with a crab spider there.  But this time the fly, evidently initially unaware of the spider, is by now all too very much aware of it!
