    Swallowtail butterflies and Lorquin’s Admirals are in full swing just now.   Jochen Möhr counted seven swallowtails simultaneously on June 6 at the intersection of Metchosin and Lagoon Roads. He shows photographs of two individual Pale Tiger Swallowtails.

   Jeremy Tatum reports that on the evening of July 6 there were still a Red Admiral and a Pacific Coast Lady on the Mount Tolmie reservoir, still flying strongly, although beginning to look a little beyond their Best Before date.

Judy Smith found a cluster of Ladybird Beetle eggs of a leaf of one of her tomato plants in Victoria.  I think, writes Jeremy Tatum, that these are probably the introduced Asiatic Harmonia axyridis, because I believe the eggs of most of our native ladybirds are rather more elongated than these are.

Jeremy Tatum writes:  Mount Tolmie this evening, 5:45 pm,  one each of Western Spring Azure, Pacific Coast Lady, Red Admiral, Lorquin’s Admiral and a few Western Tiger Swallowtails.

Jeff Gaskin writes:   Today, June 6, there was a Common Whitetail in Cuthbert Holmes Park.  Also, here today were an Eight-spotted Skimmer and several Blue-eyed Darners.   Butterflies were the usual 5 or 6 Lorquin’s Admirals, some Western Tiger Swallowtails and a few Cabbage Whites.

    Some good news from Ron Flower:  On June 5 we stopped into the small native graveyard on West Saanich Road and happily found at least three Field Crescents.

Not so good news is that we seem to have lost the Colwood turn-off colony of Silvery Blues.  There are few Lupins there now, and, in several visits this year and last, there have been no sightings of adults or ova.    Perhaps someone might check the Koksilah Road colony soon.

We are approaching the end of the Western Spring Azure season.  Jeremy Tatum writes:  I saw one yesterday at Swan Lake.  Let us know if any further ones are seen.

More nice pics later today…

    We open this morning’s posting with the successful identification by Dr Rob Cannings and Bill Savale of what we regard as rather obscure organisms, which we initially thought no one could possibly identify!  First is a Pacific Forktail damselfly bearing some small objects on its underside, photographed by Gordon Hart  in the Highlands on June 4.  Dr Cannings writes:

 

These are the sessile larvae of aquatic mites (adults are free-living in the water) in the genus Arrenurus. They are common on the adults of many Odonata species. See  Hydrachnidia – Wikipedia  and 300.pdf (indiabiodiversity.org)

This mite genus also attacks other insects with aquatic stages in their life cycles, such as mosquitoes, chironomids, aquatic Hemiptera, and so on.

The other obscure organism was some galls found on the leaves of Sasaktoonberry Amelanchier alnifolia by Aziza Cooper.  These were identified by Billl Savale as galls formed by the gall midge Blaesodiplosis sp.
