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 (jtatum@uvic.ca). 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.

[There was no Invert Alert for August 15.]

 

From Gordon Hart:

 

Hello Butterfly Counters,

The August count runs nine days from the third Saturday, August 18, to the fourth Sunday, August 26. You can submit a count anytime over this period, and you can do more than one count, just use a separate form for each count. In the case of repeat counts, or more than one person counting an area, I will take the highest count for each species.

Please use the form at http://www.vicnhs.bc.ca/?p=33 on the Victoria Natural History Society website. If you have a zero count, or just one or two butterflies, you can email me directly.

The count area is the same as the Christmas Bird Count circle (attached). For butterfly identification, the Garry Oak Ecosystems Recovery Team (GOERT) has a useful chart of butterflies of southern Vancouver Island and the Gulf Islands: http://www.goert.ca/documents/Butterfly_ID_sheet.pdf

 

If you would like a suggestion for an area to count, please send me an email.

In addition to the counts, a monthly butterfly walk is held on the first Sunday of each month – the next walk will be on September 2. We start at the summit of Mount Tolmie at 1pm, and decide where to go from there. I will send out another reminder near the month-end.

Thank-you for submitting your sightings and happy counting!

Jochen Möhr did well last night with his moth trap in Metchosin:

 

10 Tolype distincta

2 Perizoma curvilinea

2 Neoalcis californiaria

1 Drepanulatrix monicaria

1 Eulithis xylina

1 Nemoria darwiniata

 

Here are three of the pictures that he obtained.  The first two are Neoalcis californiaria and make an interesting contrast to Thomas Barbin’s dark specimen shown on August 14.  The first of these shown below is fairly typical in this area.  The second is a rather pale or perhaps faded example.  The third photograph, identified by Libby Avis as Caradrina montana, is a new one for this site.

   Kurtis Herperger sends a photograph of a beetle that came to his moth trap in the Highlands last night.   Thanks to Scott Gilmore for help with the identification as  Trichocnemis spiculatus.

   Rosemary Jorna sends a picture of a female Common Whitetail (which isn’t nearly as common as some of our other dragonflies !), which was cruising in her yard yesterday Aug 15  2018 in the Kemp Lake area.

   Jochen Möhr sends some photographs of moths from his Metchosin home last night.  In addition to these he had no fewer than 12 (!) Tolype distincta there.

    Last month Jochen Möhr subnitted some pictures of a spider from his home in Metchosin.  Dr Robb Bennett writes:  These are nice images. It would be nice if there were some indication of the size of the spiders.   However I’m pretty sure they are Parasteatoda tepidariorum. A cosmopolitan house spider – I usually see them under window sills or eaves where they have their retreats. Their prey capture webs are long sticky silk strands that extend down to the ground. They are quite efficient – I have seen lots of giant house spiders and big beetles in their webs and have heard reports of them even capturing European Wall Lizards.  

 

   Jeremy Tatum adds:  According to Web entries they can also inflict a fairly severe bite.  One site says severe pain for 16 hours.   I don’t know if this happens very often, but I thought I should mention it so that viewers can be suitably circumspect if they come across this spider.

  Mike Yip writes from Nanoose Bay:  Scores of Woodland Skippers in the garden with the occasional Pine White and Cabbage White.   A few Common Woodnymphs flying by but no nectaring or basking.

   A rare full upperside view, showing that the Branded Skipper is by no means the only skipper whose male is conspicuously “branded” with androconial scales, which release male hormones to advertise his presence.

   Jeremy Tatum shows a White-lined Hawk Moth, which came from the caterpillar shown on July 15 and the pupa shown on July 25.  The caterpillar was found at McIntyre reservoir, which is where I released the moth today.  Larval foodplant – Epilobium.
