St George’s Day

Libby Avis sends two photographs of a male Ceanothus Silk Moth Hyalophora euryalus taken in Port Alberni today (April 23).  She writes: This was a real treat – we don’t see it very often! Five years since our last sighting, but I opened the front door this morning and there it was. Just had time to take a few photos. It was slowly opening and closing its wings and was gone five minutes later.

   Aziza Cooper writes:  At the summit of Mount Douglas, on Thursday, Apr. 21, there were:

2 California Tortoiseshells

1 Painted Lady

1 Red Admiral

1 Western Spring Azure

1 Sara Orangetip

Here are photos of the Red Admiral and the two California Tortoiseshells perching near each other. Getting the two together is quite rare since they mostly seem to be madly dashing around the top of the hill.

Today, April 23, Aziza continues, I found an Autographa californica on the west slope of Mount Douglas.

   Thomas Barbin sends photographs of a few arthropods observed on April 21 in the Highlands District.

   Robb Bennett writes that the spider is probably a male Evarcha proszynskii, though he cannot be completely sure of this.

   Annie Pang recently photographed a robber fly, and she (and InvertAlert!) are grateful to Rob Cannings, who supplied the following identification and comments:    The robber fly is a species of Nicocles. It’s a female and is probably N. canadensis, although the species (and especially females) are often difficult to identify even if one has a specimen under a microscope. There are several species in our area. They all have dark markings on the wings and males have the last couple of abdominal segments flattened and silver coloured. The only reddish species, Nicocles rufus, in Canada is restricted to dry habitats on the BC southwest coast.

   Nathan Fisk writes:  Had a fantastic day in the hills around Thetis Lake yesterday (April 21) – so many creatures around. Saw a pair (male/female) of Propertius Duskywings sunning, both male and female Western Spring Azures sunning, two Cabbage Whites floating, Grey Hairstreak feeding on Spring Gold and two or three Pale Tiger Swallowtails sunning on fresh oak leaves. To cap it off I observed a Red Admiral back at Fort Rodd getting the last of the days heat.  What a day!

Annie Pang sends a photograph of a green lacewing  from Gorge Park, April 20.

      Scott Gilmore writes:  There are lots of things flying in the late afternoon in Upper Lantzville over the last few days. Some of the good stuff includes

1  A new beetle family for me Heteroceridae, the Variegated Mud-loving beetles.

2. Cryptarcha ampla.

3. A wasp from the genus Atanycolus was found flying in our house. Thanks to Ross Hill for the identification.

   Jeremy Tatum comments:  I hope viewers appreciate just how small the insects are that Scott is managing to photograph!   Another thing to appreciate is that braconids are constantly in motion.  Many braconids are parasitoids of moth caterpillars, so I see them fairly often, though I think this one is a beetle-grub parasitoid.

   Rosemary Jorna writes:  15 to 20 of these were crawling over the stucco of our home near Kemp Lake on the evening of April 20 .   Scott Gilmore writes: This is Agriotes lineatus, a European introduction that is very common in gardens and around homes here on the island. The species is identifiable from the variable width and colour of the striae (lines) on the eltyra.

   Jeremy Gatten writes from Saanichton:   I had my first Coryphista meadii last night (April 20) – two or three actually. 

   This species can be difficult to distinguish from Triphosa haesitata, so Jeremy Gatten has sent us a straight photograph of Coryphista meadii plus a copy of the photograph in which he has circled two features that he finds to be indicative of Coryphista meadii, namely the black discal spots and the short tooth on the hindwing margin (gives an uneven pattern, whereas Tissue Moth seems regularly toothed).

   Jeremy Tatum writes that he, too, had his first Coryphista meadii of the year on April 21 – as in the photograph below.  Probably not much help for identification!

   They were on the underside of a Mahonia leaf near Munn Road.

   Jeremy Gatten also found a micro moth, which he describes as "quite a nice sight last night – it is Retinia picicolana."  He writes:  I don’t know anything about its life history, but it appears to have a distribution from southern BC through California (not sure if it extends beyond to the south).  The fuzzy little orange head gives it a rather endearing quality.

   [Jeremy Tatum remarks:  I have had one or two tiny micro moths in my apartment recently, also with fuzzy little orange heads.  But in that case (Tineola besselliella, the Common Clothes Moth) neither the fuzzy little orange head nor anything else gives it, in my view, any endearing quality!]

  Jeremy Tatum writes:  Today, I did a Butterfly Count along the Pathfinder Trail (along one of the hydro lines off Munn Road).  Besides Sara Orangetips and Western Spring Azures, I encountered several (not quite all) of the local Small Brown Jobs – Western Brown Elfin, Moss’s Elfin, Cedar Hairstreak, Two-banded Grizzled Skipper, Propertius Duskywing.  I also saw several day-flying geometrids:  Mesoleuca gratulata, Rheumaptera hastata, Leptostales rubromarginaria, Epirrhoe plebeculata.

   Jody Wells spotted a California Tortoiseshell on Mount Douglas on April 20, as he writes: “begging to be photographed”.

   Jeremy Tatum photographed this White-shouldered House Moth Endrosis sarcitrella at his Saanich apartment, April 20.

Annie Pang photographed a bumblebee at Gorge Park, April 18.   We are grateful to Jared Amos for suggesting that it is a good match for Bombus fervidus

Jeremy Tatum writes:  At 6:30 this evening, April 20, there were 2 California Tortoiseshells, a Red Admiral and a Mourning Cloak together on the Mount Tolmie reservoir, as well as a Painted Lady near the Jeffery Pine.  And earlier in the afternoon there were two Mourning Cloaks near the Swan Lake nature house.

Jeff Gaskin sends the following sightings:  On April 18, a Sara Orangetip at the Interurban campus of Camosun College.  On April 19, a Mourning Cloak over Bowker Avenue.  And on April 20, while on a walk along Hector and Conway Roads, he recorded 1 Propertius Duskywing, 3 Sara Orangetips, 6 Cabbage Whites and 29 Western Spring Azures.
