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.

   Heather Proctor gives a probable identification of the mites on Ren Ferguson’s July 27 photograph of a long water scorpion. Scroll down to July 27 to see.

 

   Today’s (July 30) issue of the Times-Colonist page D2 carries an item about a nature photographic contest organized by the SPCA.  Proceeds from the competition go towards WildARC.  Insects are included in the eligible subjects. (It doesn’t mention other invertebrates!)  The quality of photographs submitted to our Invert Alert site is exceedingly high.  I would encourage contributors to have a go at the SPCA competition.

 

   Jeremy Tatum writes that he found a caterpillar of a Red Admiral at Witty Beach Road, Metchosin, today.

 

   Bill Katz sends a photograph of a Panthea sp. from Goldstream Park.  It closely resembles the moth that I (Jeremy Tatum) posted on June 24 and which I labelled P. virginarius.  However, I am now wondering of both of them might in fact be P. acronyctoides.  Am looking into it, and will post if we make any progress!

   Bill also photographed a caddisfly at Goldstream:

   Ren Ferguson photographed a spectacular Sphinx perelegans on her railing on Salt Spring Island, July 29.

   Of the next one, Ken comments that “it is the neatest geometrid I have seen in a while.”

The caterpillar of this moth is even more remarkable.  We’ll have to look out and see if we can find and photograph one.  I think the colour pattern of the moth is what is called “disruptive coloration”.  It divides the moth into two sharply demarcated areas, neither of which has the shape of any sort of insect or edible morsel.

    Jeremy Tatum writes:  I visited Mount Tolmie just after 6:00 pm today.  There were one or two Painted Ladies and Red Admirals on the reservoir or flying around the Jeffery Pine, and at least one West Coast Lady on the reservoir.  Also, just outside the entrance to the reservoir, flying around or perching on the Mahonia or the Laburnum, a pristine fresh Anise Swallowtail.  I wonder if it had bred on the hill, perhaps on one of the numerous Fennels there.  Also below, a very young caterpillar of a Western Tiger Swallowtail found on willow at Panama Flats. Botanists might be interested to see the huge expanse of Alisma plantago-aquatica there at present.

   Ren Ferguson sends some photographs taken on Pender Island on July 4 in brackish marsh habitat.  We get very few aquatic animals on this site (challenge for photographers – please note!) so we welcome Ren’s photograph of a long waterscorpion Ranatra sp.  I don’t know if we’ll be able to go below genus level.   Dr Heather Proctor writes, of the red dots:

The red blobs are water mites, and it’s 90% likely that they are Hydrachna (Hydrachnidae), which are the most common water mites parasitic on Hemiptera. But without a closer view I can’t be absolutely certain.

Thomas Barbin sends a varied collection of insect close-ups.  The first one from Pender Island, June 10:

   We have seen before on this site photographs of crab spiders overcoming much larger bees and wasps.  This one is another spectacular example.  Photographed in the Highlands District, June 21.  The bee is Bombus sp. (mixtus, flavifrons and ternarius all look like reasonable fits) and the spider is Mecaphesa sp.

   Aziza Cooper sends a photograph of a teneral damselfly from Martindale Road, July 23.  Aziza writes that there were 45 Cabbage Whites over the cabbage field there.  Rob Cannings writes:  Yes, this is a teneral… (an individual, soon after moulting/emergence, whose cuticle is almost colourless and still unhardened). This is a male Tule Bluet Enallagma carunculatum. In this species, the superior appendages (cerci) are distinctive and are visible in this photo The middle abdominal appendages have much black dorsally, more than the other common local species have.

   Gordon Hart writes:

 

The July count tallied 12 species, one fewer than 2016. This year, there were no Satyr Commas or Mourning Cloaks, but we added one Ringlet (Large Heath). Total numbers were up by about one third, from 667 to 1046 individuals. Cabbage Whites were the most numerous with 570 (2016: 431), and Western Tiger Swallowtails were next with 140 (2016: 47). Woodland Skippers started to appear near the end of the count period and only nine were counted (2016: 45). More Pine Whites were seen this year than last (2017:72, 2016:52), mainly due to large numbers seen in Colwood by Jeff Gaskin.

Thanks to everyone who submitted counts.

Here’s a Chalk-fronted Corporal that I photographed at Spider Lake yesterday.  There were several of these about alongside Eight-spotted skimmers, Blue-eyed Darners and Northern Bluets.  Spider Lake is near Horne Lake north of Qualicum Beach close to Highway 19.

   Return to back-to-business provides an opportunity for a brief reminder of the optimum way of submitting observations to Invertebrate Alert.  Send observations to jtatum at uvic dot ca   We welcome, of course, reports just of sightings and they don’t have to be accompanied with photographs.  If you send a photograph or photographs, please send them in .jpg format as an attachment. It takes me much longer to process if you send them some other way. Remember to say where you saw the animal (not “my backyard” – I don’t know where that is) and when (date with month written in letters!).  Unless I have a query, I don’t generally respond – your “reward” and thank you are when the item gets posted!  There may sometimes be a delay, while we are trying to identify an obscure insect, though if the delay is over a week you might check with me in case I have overlooked the record (which occasionally happens).  If you know the identification of the insect, please say so – so that I don’t have to spend time figuring it out myself!  If you don’t know, we’ll do our best – that may take a few days.   Jeremy Tatum

 

  Bryan Gates sends a photograph of a European Paper Wasp. He writes that for the past four years the species has been nesting in a hollow aluminium railing at his house in Black Creek.

   Val George sends photographs of two moths from his Oak Bay house, July 21.  He also sends a photograph of a Great Arctic butterfly from Mount Washington, seen on the VNHS Botany trip to Mount Washington, July 23, thus again dashing my (Jeremy) theory that this species occurs only in even-numbered years!

   Jochen Moehr sends a picture of a crane fly from his house in Metchosin, July 9.  Alas –  in spite of the efforts of the best brains in Victoria, the exact species identity of this well-marked insect still eludes us.

   New VNHS member Michael Croteau photographed a syrphid fly on Mount Work on June 3.  We are grateful to Jeff Skevington and Andrew Young for the identification as a male Melanostoma sp.  Dr Skevington advises us that Melanostoma  is probably a complex of species, but at present they are all lumped as M. mellinum.
