   Jeremy Tatum writes:  A while ago a friend dug up some pupae in her veggie garden in Victoria.  One of the moths emerged two days ago, and its identification stumped me.  I consulted Jeremy Gatten, and he got it – it is Apamea cuculliformis.  Thank you, Jeremy.

   One May 18 we mentioned how good it has been for lycaenids recently.  Here are three more from Rosemary Jorna in the Sooke Hills.

    And yet another, from Val George, one of two Purplish Coppers that he saw at Island View Beach on May 19, this one a female.   Also there, he writes, was a Coenonympha tullia  (a.k.a. Large Heath or “Ringlet”).

   In addition to these little lycaenid jewels, we also seem to be having lots of reports of the big sphingid and saturniid spectaculars recently.  Val George found this one at Cattle Point on May 19.

   Jeremy Tatum writes:  A Red Admiral and a Mourning Cloak from Lochside Drive between Blenkinsop Lake and Lohbrunner’s this afternoon.  I also went to the Mount Tolmie reservoir at about 3:00 pm, but there were no hill-topping nymphalids there.  Too early in the afternoon.  I bet there’ll be lots of them there at 5:00 pm.  There were two Western Tiger Swallowtails flying around the periphery at 3:00.

   Aziza writes: I saw a single Silvery Blue on Sunday afternoon along the Galloping Goose trail. It was at a lupin patch near the Colwood exit, where Craigflower meets Sooke Road. Easiest access is to park at the east end of Atkins Road and walk east for 1/2 block.

   Jeremy Tatum writes:  It seems to be a good weekend for lycaenids.  Yesterday I saw one each of Western Brown Elfin, Moss’s Elfin and Grey Hairstreak along the Pathfinder trail at Munn Road, and of course several Western Spring Azures.  And today, Monday May 18, there are still hilltopping nymphalids on the Mount Tolmie reservoir in the late afternoon – Mourning Cloak, Painted Lady, West Coast Lady.

   Mike Yip writes (May 16):  I was hoping for a duskywing, but I was deceived several times by a dark brown day-flying moth today on the road to Rhodo Lake (Nanoose Bay).


   Jeremy Tatum remarks:  Well that is precisely what is supposed to happen!  According to Powell and Opler: “In flight the adults could be confused with adult duskywing skipper butterflies”.

  Jeremy Tatum writes:  Here is a Cerisy’s Eyed Hawk Moth from my Saanich apartment, May 16:

   Jeremy continues:  Although we have had a great variety of creatures on this site, so far we have had very few aquatic animals, so here’s a challenge for photographers (not to say for identifiers!)  I had my first (poor!) try at photographing aquatic insects yesterday.  They were incessantly active and just would not stay still.  I eventually got some poor shots of a couple of damselflies and a beetle from Beaver Lake Ponds.

    Rob Cannings writes:  Both larvae are quite young (wing sheaths hardly developed). I assume they are all local? The first larva is in the genus Lestes, but I can’t tell which species from the photo. Lateral views of the gills and ventral views of the labium help, but in general, most damselfly and dragonfly larvae are awfully hard to identify to species from photos. The second species is in the family Coenagrionidae, and I’m guessing it may be Ischnura cervula, but I can’t be certain.



    I set Scott Gilmore perhaps an even more difficult poser by photographing an aquatic beetle larva.  He writes:  Larvae are tough but this must be Dytiscidae. There is no way I could go past that!

   Jeff Gaskin writes:  Sunday May 17, a Mourning Cloak flew down Wascana Street just before 3 p.m. Wascana Street is in the Gorge/Burnside community.


   Yesterday,  Saturday May 16, a check for Silvery Blues at Helmcken Road and the Island Highway. and also at the Colwood turnoff, was negative. I could not find a single one. I’m not sure if it was because it was around 4 p.m. or they just haven’t appeared yet. There’s an outside chance that they’re already finished for the season too. I’ll check again later in the week  –   I sure don’t want to miss these guys.


   And finally, to round off the day, a caterpillar and a fly.
