   Here is Gordon Hart’s report of the September VNHS Butterfly Count.

There were 19 reports from 21 locations by 11 observers for the last 2017 butterfly count from September 16-23. Those numbers were similar to 2016, but the number of butterflies counted was exactly double 2016: 246 this year vs 123 last year. Last year only two species were found. This year, there were seven species, including 28 Painted Ladies. Cabbage Whites were also more common with 205 counted this year, 83 more than last year. I plan to submit a summary of all the 2017 counts in the January issue of The Victoria Naturalist while we wait for the next butterfly season. Thanks again to all the participants!

Butterfly count coordinator.

   Apologies – I have been out of action for a few days.  Big backlog on my computer, so I hope I don’t inadvertently miss some contributions.  E.g., I think I missed Rosemary Jorna’s spider below some days ago.

   October is the month for Banded Woolly Bears, the caterpillar of the Isabella Moth.   Here is one found near the Red Barn at Tod Flats by Jody Wells.

   Scott Gilmore writes from Upper Lantzville:  I was surprised to find three small weevils inside a red pepper. The peppers had been grown in California and I assume they must be the Pepper Weevil, Anthonomus eugenii.  Jeremy Tatum ponders:  If they were found on Vancouver Island, but were imported from California, are they eligible for posting on Invert Alert?  I took one look at the first charming photo below and immediately decided yes!  You just have to love it.  According to a Web article, the length of the weevil varies from 1.5 to1.8 mm.  (Have a look at a ruler to remind you of how small this is.)

   Aziza Cooper writes:  On October 15 I found two flies at Lochside Trail near the pig farm. They were in a weedy patch diagonally across the trail south of the pig farm. (The pig farm is south of Martindale Road.)  Also on October 15 one moth was along McIntyre Road near McHugh Road, Central Saanich,

 

  Jeremy Tatum writes.  The first fly is Eristalis tenax.  I think we’ll have to leave the second one as just an unidentified fly, unless anyone has a suggestion.  Because of the yellow colour (which I think is at least partly pollen), I had at first thought of Scathophaga stercoraria, which is common at the pig farm, but it’s the wrong shape and the eyes are too large.  The moth is a rather worn  Noctua pronuba.

   Jeremy Gatten writes:  The nice weather yesterday resulted in a surprising number of dragonfly and butterfly species on the wing today.  The highlight of my day was my first American Lady for BC, which was at Albert Head Lagoon.  Also at Albert Head Lagoon were several Cabbage Whites, a female Common Green Darner and what I believe was a Paddle-tailed Darner.  At Witty’s Lagoon, I had one Cardinal Meadowhawk and a few Autumn Meadowhawks. [The Autumn Meadowhawk is also known as the Yellow-legged Meadowhawk Sympetrum vicinum.] Moving on to Swanwick Road, I had a Painted Lady and a Striped Meadowhawk.  Reasonable numbers of moths around at Hans Helgesen Elementary School, including: Agrochola purpurea (2), Orthosia mys (3), Epirrita autumnata (4), Philedia punctomacularia (1), Tetracis sp. (3, possibly two different species), and Eupithecia unicolor (1).  At my place in Saanichton this evening (October 15), I’ve had: Autographa californica (2), Sunira decipiens (1), Mythimna unipuncta (2), and Eupithecia sp.

The third is a species of  Drepanulatrix – a genus which has been providing us with identification problems.  In order of increasing preference, Jeremy Tatum writes, I would identify Jochen’s moth below as one of D. foeminaria, D. secundaria, D. monicaria.  Actually I’m sufficiently sure that it is Drepanulatrix monicaria that that’s how I’m going to label it,

At least seven butterfly-ers visited McIntyre reservoir today, and saw several Cabbage Whites, three Orange Sulphurs (at the north end of the reservoir), a Painted Lady (on the west side), and many Autographa californica.   Kirsten Mills saw a Painted Lady at Prospect Lake Golf Course, and another one at the corner or Tillicum Road and Gorge Road.

   Nathan Fisk sends an interesting picture of a cell from the nest of a leafcutter bee.  He found three of these cells in the soil at Fort Rodd Hill Nursery. The cell will be provisioned with nectar and pollen, and one egg will be laid inside it.  The bee larva will grow within.  The sides of the cell are constructed from roughly rectangular portions of a leaf, and the ends are constructed from circular portions.  Leafcutter bees are regarded as major pollinators.
