Well, one never knows what might be reported to an invertebrate site, and today we have our first report of a non-arthropod, and an animal I was not expecting. Bill Savale reports a group of rotifers from an unlikely location – high up on the dead stalks of Scentless Mayweed (Matricaria inodura) at Panama Flats. He showed them to me, and I must say that it was a “lifer” for me – one does not often get a Class lifer. Bill says that the Order is Bdelloidea, the Family almost certainly Philodenidae, and the Genus maybe Philodena. True to form, the two circlets of cilia at the head end really did look like whirring wheels, and they were very efficient at pulling in the bacteria visible under the microscope.

Bill Dancer writes: Just to let you know that ten Tuesday birders and I saw our first very healthy looking Mourning Cloak at the SW corner of Rithet’s Bog on the 23rd March. I thought this was early, but then this has been a nice El Nino year. It was flying along the dyke that runs parallel to Chatterton Way.
Jeremy Tatum writes: I saw my first butterfly of the year on March 27 – a California Tortoiseshell hill-topping at the very summit of Mount Tolmie. On the same day two moths visited my apartment - Egira curialis and Endrosis sarcitrella. E. Curialis is one of a group of noctuid moths known as “woodlings” that fly early in the spring. The caterpillars regularly feed on the flowers of the Welsh Poppy in our apartment garden. E. sarcitrella (Oecophoridae) is the White-shouldered House Moth, and I hate to think what its caterpillars might find to eat in my apartment.

Joy Finlay reports Sara Orange Tips at Thetis Lake yesterday.
Annie Pang sends a fine selection of butterfly photographs taken on March 24, while many of us are still looking for our first butterfly! They are: Western Spring Azure and Western Brown Elfin at Esquimalt Gorge Park, and California Tortoiseshell and Sara Orange Tip at Christmas Hill, Saanich. She also saw an Anise Swallowtail on Christmas Hill.

I still haven’t seen a butterfly, but they are starting to appear in earnest now. Annie Pang reports a Western Brown Elfin and a Western Spring Azure at Gorge Park, a Cabbage White at Playfair Park, and California Tortoiseshell, Anise Swallowtail and Sara Orange Tip on Christmas Hill.
Meanwhile we have our first non-insect invertebrate photograph in the site, as well as our second bug. Terry Thormin writes: “I spent part of this afternoon at Cumberland Marsh looking for birds and insects. A fifteen minute sit at the edge of the marsh resulted in these two photos. I am not sure what the gerrid (water strider or pond skater) species is, although I would guess Gerris remigis. Is there anyone knowledgeable in gerrids in the group?”

While the site was originally intended to cover just the southern Vancouver Island birdwatching area, how could one turn down Terry’s great photos?! Therefore, as long as I’m not encroaching on anyone else’s territory (and please do let me know if I am) I’ll include, for the time being, contributions from anywhere on Vancouver Island.
A problem with butterflies is that it is literally true that no two books use the same set of names, either English or scientific, and we have already had different contributors to this site using different names for the same butterfly. In order to try to have some sort of uniformity, I shall shortly post a list of butterfly names that I propose to use on this site. Comments will be welcome, but just remember that it will be well-nigh impossible at present to come up with a list of names that everyone will agree with for all species!

Gerry Ansell reports two Sara Orange Tips at Mount Douglas today, and two Brown Elfins (or, if we follow Cris Guppy, "Western Elfins") at Cordova Ridge Saanich, and he sends a nice photo by Wendy Ansell of one of the elfins.

Annie Pang sends a photo of Mesoleuca gratulata from Seymour Hill taken today, accompanied by one of her charming verses. Notice the egg that the moth has just laid on the Bramble bud.
Terry Thormin sends three photos, one of bumble bee and two of the same ichneumonid. He writes that "both species have been around for awhile, but I just got photos today. The ichneumonid was ovipositing in the sand at the base of a small plant that I could not identify. Because it moved from plant to plant I suspect that it is going after an insect larva that is host specific to that plant. The bumble bee is on Gold Star, and because the plants are so small, every time the bee landed its weight would cause the flower to bend upside down. Both insects were photographed at the sand dunes at Point Holmes in Comox." Would anyone like to have a go at identifying them?
Dave Stirling writes that he saw a female Western Spring Azure taking the sun on a low Garry Oak branch, near Wain Road, North Saanich, on March 20. March 18 March 12
Terry Thormin asks if I can expand the area covered by this site to a larger area of Vancouver Island or even the entire Island. I’m not sure whether I should say yes or no, but I can’t resist posting the superb photos that Terry has submitted. His Honey Bee Apis mellifera and Drone Fly Eristalis tenax were photographed in Comox on February 17, and his unidentified (yet) syrphid was photographed there on March 5. Can anyone identify the syrphid for sure?
One of the great spectacles of nature to be seen this week is the large numbers of Yellow Dung Flies Scatophaga flava to be seen at the pig farm at Lochside Drive, Central Saanich. These may not be to everyone’s liking, but it really is spectacular, and worth going to see. If you look carefully there, you can also see a few Eristalis.

No viewer of the site managed to identify Terry's syrphid. This may have been because I had messed up the posting and left you all with a blank rectangle to stare at, which put viewers somewhat at a disadvantage. Meanwhile Terry has consulted syrphid expert Martin Hauser, who identifies it as Eupeodes sp., probably E. americanus.
Terry also sends a picture from his Comox garden this morning of a Western Conifer Seed Bug Leptoglossus occidentalis. Wouldn't it be nice if we could persuade everyone not to use the word "bug" for any old insect, but to use the word "bug" when they mean "bug"!

I have yet to see my first butterfly, but I found two noctuid caterpillars. One was a Large Yellow Underwing Noctua pronuba walking along the sidewalk next to Shelbourne shopping plaza on March 7. It was in too much of a hurry for photography, but you can read about the recent arrival in our area of this European moth in an article by Claudia Copley and Rob Cannings at http://www.sfu.ca/biology/esbc/Journal/journal2005/2005_83-84_Copley.pdf. Caterpillars of Aseptis adnixa are now to be found on the young leaves of Indian Plum. You can see from the shape of the head capsule of the one that I photographed near Blenkinsop Lake on March 7 that it is waiting for ecdysis (skin-change), and it obligingly sat still for me.

March 3 We just got our first posting, from Sharon Hartwell, who tells us that on February 20 she saw her first two Satyr Anglewings of the year on Lone Tree Hill. Has anyone else seen any butterflies yet? I haven't -- I'm still waiting. On February 27 I saw a Banded Woolly Bear at Panama Flats -- that's the caterpillar of the Isabella Moth Pyrrharctia isabella. So let us know what else is out there! Jeremy Tatum |
