   Jeremy Tatum writes:   Back from holiday in England.  Sorry for the hiatus in Invert Alert, but we are ready to get going again.  On my first full day in Sussex, England, August 11, I saw 12 species of butterfly.  This made me feel guilty, because I had arranged a day out on August 13 with David Harris, Sussex butterfly enthusiast, and I was afraid that I had seen so many species that there wouldn’t have been any left for David to show me.  How wrong I was!  On August 13 he showed me an additional 14 species – so that was 26 species in two days!   Thank you, David Harris, for setting aside a whole day to go out a-butterflying with me!

Now back to Vancouver Island.  Just before I left, I inadvertently missed out an observation from Gordon Hart of a Grey Hairstreak in his Highlands garden, August 6.

On August 8 we posted photographs from Annie Pang of a brilliantly coloured halictid bee, Agapostemon texanus.  Annie’s photo was of a male, with a banded abdomen.  Aziza Cooper managed to get a quickie photo, at Swan Lake on August 8, of a very active female – whose abdomen is the same brilliant green as the head and thorax.

Aziza also sends a photo of a caterpillar of the Spotted Tiger Moth from the railing of the wooden boardwalk at Swan Lake, August 22.

   Aziza Cooper reports a Red Admiral and a Woodland Skipper from the tip of Sidney Island Spit, August 27.

We also have photos of grasshoppers and bush crickets waiting in the Invert Alert Inbox – but they will have to wait for another day, while we try to get them identified.

HOLIDAY!

   Jeremy Tatum writes:  Just a reminder that I’m going on holiday – to England – tomorrow, and consequently I shall not be running Invertebrate Alert until I get back on August 27.   By all means continue to send in observations and photographs during this time (but they will not be processed or posted until I get back), but please try and restrict yourselves to truly noteworthy observations and your best photographs, and try not to overwhelm me with oodles of photographs of our most frequently-photographed insects!

It will still be of interest, of course, to try and record the dates of the latest Lorquin’s Admiral and Western Tiger Swallowtails.  That reminds me that I saw a Lorquin’s Admiral at UVic today, shortly before I came into the office to type this posting.  And Jeff Gaskin reports a Western Tiger Swallowtail today from Gorge Park across from Millgrove Avenue.

Gordon Hart reports on yesterday’s (August 7) VNHS Butterfly Walk as follows:

Despite a cloudy start to the day, by 1 p.m. the sun had appeared and we saw our first butterfly on Mount Tolmie- the Anise Swallowtail around the fennel at the summit. [Jeremy Tatum remarks: The Anise Swallowtail is at least partially bivoltine, so it is quite possible that it may be thinking of laying eggs on the Fennel there.  Might be worth searching for.]   Two more butterfliers (Val George and Aziza Cooper) joined me and we went out to Island View Beach, where we found at least 10 Ringlets (Large Heaths) in the meadows along the way, and a total of 15-20 by the end of the trip. We did not find any Purplish Coppers so perhaps their season is over. We arrived at the spit by the sewage plant parking lot and saw lots of Woodland Skippers. We started looking at each skipper carefully. Val found the first Western Branded Skipper, I found one sunning on the path and Aziza found a third one nearby. These were all along the fence line on the way out to the tip of the spit in the general area where Steve Ansell and Val had seen them recently. The only other butterflies we saw were four Cabbage Whites.  Later, Aziza saw a Red Admiral back at Mount Tolmie.

   Aziza adds:  Sand Wasps with banded abdomens were common on Gumweed north of Island View Beach.

   Jeremy Tatum writes:  I recently had a little discussion with Sean McCann about the spelling of Bembix.  Bembix, Bembex and Bembyx are all to be seen, and each of these spellings could be defended as the “correct” one.   Current usage, at least in North America, seems to favour Bembix.

Annie Pang sends a photograph of a colourful male sweat bee (Halictidae) from Gorge Park, August 7, identified by Annie as Agapostemon texanus.

   Val George writes:   Yesterday morning, August 4, I had a Grey Hairstreak in my garden in Oak Bay.

Jeremy Tatum writes:  Yesterday evening there were two Red Admirals flying around the top of Mount Tolmie, and today I saw a Western Tiger Swallowtail and a Common Green Darner in Uplands Park.

Is anyone seeing any Pine Whites?   Jeremy Tatum writes:  I may have briefly seen about two this year, but that is all.  Let us know if you are seeing any of this usually common July/August species.

Cheryl Hoyle sends a photograph of a grasshopper taken in Metchosin, today, August 5.  Claudia Copley writes:  This is hard – it would help to see the lower hind leg colour and the hind wing.  I am certain about the tribe (Trimerotropini) and am leaning toward Carolina Grasshopper Dissosteira carolina.

Monthly Butterfly Walk

All Welcome!

Gordon Hart writes:

The monthly butterfly walk will be this Sunday, August 7.  We will meet at Mount Tolmie at 1 p.m. at the main parking lot below the summit on the north side and decide where to go from there.  The trip is weather-dependent, so if it is too cool and cloudy or rainy, we will probably have to look for birds instead!  I was thinking perhaps Island View Beach and Cordova Spit might be good.  There’s a chance of Purplish Copper, Anise Swallowtail, Large Heath (“Ringlet”) and the rare Western Branded Skipper.

Jeremy Tatum writes:  Not many moths recently, but, in several places I have seen the big silken nests of the Fall Webworm Hyphantria cunea (Lep.: Erebidae – Arctiinae).  Also, if you see a smallish dark reddish-brown moth flying rapidly around in a corkscrew-like fashion, which you first think might be a skipper, though its flight doesn’t look quite right, you are probably seeing a male Vapourer Moth Orgyia antiqua (Lep.: Erebidae – Lymantriinae)

   Jody Wells sends a photograph of Neoalcis californiaria from West Saanich Road near Keating Cross Road, July 31.  Jody writes:  I think it’s a beauty but some butterfliers weren’t impressed by this moth.  Jeremy Tatum writes:  Well, Jody, you and I both appreciate this fine moth, even if no one else does.  A true wonder of Nature.
