   Jeremy Tatum writes that there was a fresh Painted Lady on the Teasels at McIntyre Reservoir today.  There were still a lot of Cabbage Whites on the kale fields there.  Apart from the Cabbage Whites, we must be coming close to the last butterfly of the year.  Please keep reporting any that you see.

1 Eupithecia sp. 

2 Euxoa difformis

3 Lacinipolia pensilis

2 Xestia finatimis

 

Mike McGrenere writes:  Barb and I were at Elk/Beaver Lake Park yesterday morning  (September 6) and we came across a rather tattered Lorquin’s Admiral, the first one that we have seen in quite a while (photo attached).  I was at Swan Lakeon September 5 and I saw a Tiger Swallowtail near the parking lot.

   Annie Pang sends a photograph of a Mud-dauber Wasp, June 29 of this year – rather late to make its way into Invert “Alert”, but I couldn’t resist it.

Sonia Voicescu has been away for most of the summer, but on her return she undertook and completed the enormous task of transferring all our Invert Alert butterfly records for this year to eButterfly.  We must all be very grateful to Sonia for doing this huge amount of work.

 

Sonia tells us that this year eButterfly has so far recorded, mostly from Invert Alert, 52 species of butterfly from Vancouver Island.  Here they are:

There is room for some minor tweaking.  For example, it is perhaps a little stretch to include Cortes Island (Silver-spotted Skipper) as part of Vancouver Island.  And it is difficult to know to which species the name “Grizzled Skipper” (50) refers to, because this name, without any additional adjective, can be applied to several species, including the only one known to occur regularly on Vancouver Island, namely the Two-banded Checkered or Grizzled Skipper. On the other hand, the “splitters” might like to add an additional species to the list by splitting the Branded Skipper into Common and Western Branded Skippers, both forms (whether they be species or subspecies) occur on Vancouver Island. In any case, 52 species, plus or minus one or two, is a very exciting total, and much more that I would have guessed.

 

Are there any more that might be added?  Well, no one reported the recently re-discovered Johnson’s Hairstreak this year, nor the Phoebus (aka Rocky Mountain) Parnassian, nor the Arctic Blue, which was found a couple of years ago on a VNHS trip to Mount Washington.   So more than 52 is a year is in principle possible – but not very easy!

 

Sonia notes that there are some differences in the English names used in Invertebrate Alert and eButterfly, the most obvious of which are as follows:

 

Western spring azure ——Echo azure on eButterfly

Sara orangetip———Pacific orangetip on eButterfly

Western brown elfin——Brown elfin on eButterfly

Cedar hairstreak——Juniper hairstreak on eButterfly

Essex skipper——European skipper on eButterfly

Western meadow fritillary—–Pacific fritillary on eButterfly

Pale tiger swallowtail——Pale swallowtail on eButterfly

 

I’m not quite sure what to do about this, though I expect I shall continue to use the names we have been using.  Bear in mind that every book uses a different set of names, so that the eButterfly names are no more standard than any others.

 

Jeremy Tatum continues –  Here are a couple of caterpillars and a moth:
