While Hans Toom and Gary Murray were busy photographing birds and 
scenery on Seal Island this past weekend, I took a lead from Angus 
Maclean, and looked down.   The sheep on Seal greatly restrict the 
presence of flowers, but there were a few goldenrods that eluded the 
bovine teeth, and there were large numbers of colourful flies feeding 
on the nectar.

I have tried to identify the flies using the BugGuide on the internet 
(it is a fine site).   I have placed images of the two different 
flies I photographed on the following web page:

http://maybank.tripod.com/naturens/inverts.htm

I thought one was a Drone Fly (Eristalis tenax), and I used the 
following page for comparisons:

http://bugguide.net/node/view/7183

The following image seemed a very close match:

The other, smaller fly, I have identified as a Transverse Flower Fly 
(Eristalis transversa), and for this I used the following page:

http://bugguide.net/node/view/9099

The following image seemed a close match:

However, these flies seem to be a tricky group, so if anyone finds a 
mistake in my identification, I'd love to hear about it.

I neglected to bring my insect net, as I thought there would be no 
dragonflies, but a number were flying around, though none of them was 
strongly marked, and a few were the dreaded meadowhawks.   For 
butterflies we had many Monarchs and Red Admirals, and a few American 
Coppers, American Ladies, and Clouded Sulphurs.

Cheers,
