This blog provides an informal forum for terrestrial invertebrate watchers to post recent sightings of interesting observations in the southern Vancouver Island region. Please send your sightings by email to Jeremy Tatum (tatumjb352@gmail.com). Be sure to include your name, phone number, the species name (common or scientific) of the invertebrate you saw, location, date, and number of individuals. If you have a photograph you are willing to share, please send it along. Click on the title above for an index of past sightings.The index is updated most days.

    Re the mites on geometrid moths, as shown on July 22 and 25, I am told that “Erythraeids, particularly members of the subfamily Leptinae,  quite commonly parasitize Lepidoptera, but not with any obvious host specificity. This is probably an erythraeid based on its being bright red.  But don’t quote me!”

   -so I shan’t say who it is, other than what the press would call a “usually reliable source”!

   Jochen also writes:  Woodland Skippers have been around here for a few days now.  Today was the first time I managed to get a picture.

   Ron Flower reports that he saw no fewer than five Anise Swallowtails at McIntyre reservoir yesterday, July 24.  Jeremy Tatum writes:  Apologies for not posting that immediately – I wondered if it was a typing mistake, but it wasn’t!   They really were Anises.   I went there this afternoon, July 25, where I saw a female Purplish Copper.

 

  On July 22, we showed a photograph by Jochen Möhr of a geometrid moth with a mite on it.  Just two days later David Harris (who visited Victoria in June) sent me a similar photograph of another geometrid moth, in England, also carrying a mite.  The moth, having been photographed in England, is even more illegal on this site than Jody’s trout, but I slip it in here just for interest, and for comparison with Jochen’s.

   Gordon Hart sent a couple of photographs of a bee in his Highlands garden about a week ago.  So far they have evaded identification.  If anyone can help, please let us know.

   Yesterday sand wasps seem to have attracted the attention of photographers.  Photographs were sent by Jody Wells from Saanichton and by Annie Pang from the Gorge.  The common default species here is Bembix americana, which is what we’ll label them here, though viewers might like to be more cautious and think just Bembix sp.

   Jody Wells sends a picture of a pond skater (water strider) from Goldstream Heights, July 23.  Also intruding illegally into the picture is a vertebrate animal, which Jody tells me is a young Cutthroat Trout.

   Mike Yip writes from Nanoose Bay:  Lorquin’s Admiral, Pine White, and Cabbage White continue to pass through occasionally, but the one surprise was a fairly fresh second generation female Western Spring Azure. I also photographed one moth and three medium-sized dragonflies.

   Libby Avis writes:  This is one of the few moths that usually sits with its wings up.

   Cheryl Hoyle sends a picture of a tachinid fly from Swan Lake, Saanich, July 20.  We are grateful to James O’Hara for identifying it as Uramya halisidotae.    The Spotted and Silver-spotted Tiger moths, now in the genus Lophocampa, were formerly in the genus Halisidota, so are presumably victims of this parasitoidal fly.

   Jochen Möhr reports seeing two Panthea virginarius and one Gabriola dyari at his Metchosin home yesterday.   Gordon Hart reports seeing two Sphinx sp. at his Highlands home.   Val George writes that in the last few days at least nine or ten adult Pyrausta californicalis have appeared around the mint patch where he found the caterpillar at his Oak Bay home.

   Gordon Hart sends a picture of a damselfly from Cowichan Station, July 5.  Thank you, Rob Cannings, for identifying it for us as a spreadwing, Lestes sp.
