Jeremy Tatum sends a photograph of a small nondescript green caterpillar found at Lochside Drive north of Blenkinsop Lake.  It could be any of hundreds of species – impossible to identify.   But wait! Only three pairs of midabdominal prolegs, and feeding on Stinging Nettle.  Y’all know that this has to be Hypena  sp.

[Added later:  The adult moth emerged on August 4 and was found to be H. humuli.]

    Jochen Möhr writes from Metchosin:  Since July 17 we have had three to five Malacosoma californicum here every day – mostly females. But today, there was obviously a male. [See, among other things, its elaborate antennae.]

   Jeff Gaskin writes:  I had some good butterflies at both Swan Lake and Blenkinsop Lake today, July 18.  At Swan Lake I had 18 European (Essex) Skippers, 13 Lorquin’s Admirals, 4 Western Tiger Swallowtails and just one Cabbage White.

   At Blenkinsop Lake I found a Red Admiral and one and maybe two Satyr Commas.  Also were included 16 Cabbage Whites, 5 Western Tiger Swallowtails, and 4 Lorquin’s Admirals.

  Jeremy Tatum writes:  The little geometrid moth Idaea dimidiata seems to be quite numerous just now.  There were four of them at the back door of my Saanich apartment building this morning.  Here’s one of them:

  Jeremy continues:  This fine animal was in my bath this morning:  It belongs to the Order Zygentoma (formerly Thysanura), or Three-pronged Bristletails.   They are currently in the Class Insecta, though this could change.The Order includes “The” Silverfish Lepisma saccharina, which likes cool places, and “The” Firebrat Thermobia domestica, which likes warm places.  This one is a different but related species, sometimes called the Grey Silverfish or the Grey Firebrat.  Let’s settle here for the scientific name Ctenolepisma longicaudata

 July Butterfly Count

Message from Gordon Hart

 Hello Butterfly Counters,

The July count period starts Saturday July 16 until Sunday July 24. This is an informal census of butterfly numbers and species in Greater Victoria. The area is defined by the Christmas Bird Count circle, extending from Victoria to Brentwood Bay and Island View Road in Central Saanich, and west to Happy Valley and Triangle Mountain, and Langford Lake and Goldstream areas.

You can submit a count any time over the count period, just use a separate form for each count and location. In the case of repeat or duplicate counts, I will use the higher numbers. To submit counts, please use the form from the VNHS website at

https://www.vicnhs.bc.ca/?p=33

If you have difficulty with the form, just send me an email with the information.

Thank-you for submitting your sightings and good luck with your count.

Gordon

  Kirsten Grove-White sends a photograph of one of our native emerald moths, Nemoria unitaria from the Swan Lake Nature House today:

   [Jeremy Tatum writes:  I had initially mislabelled the above moth as N. darwiniata, and I am grateful to Libby Avis for the correction.  Libby writes:  No red markings on the body and the lower line on the hindwing starts to curve upward just before it reaches the body, whereas in darwiniata the line goes straight across to the body.]

Jochen Möhr writes from his property in Metchosin:  It looks as though the tent caterpillars – of which I counted at one time 19 colonies in the vegetation around this house – are finally ecloding.  This morning, there were five of them on the floor of the deck under the black light.  Jeremy Tatum writes:  I believe that all three of the moths below are females.
