INVERTEBRATE ALERT
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.

   Jochen Moehr sends a picture of the green form of a caterpillar of a Large Yellow Underwing from his Metchosin garden.  And he writes:  I took my dog out to Matheson Lake in the hope to get closer to Western Spring Azures than here.  In the past I had often seen them mud puddling at the beach there.  

 

   I was not disappointed.  Although – being surrounded by dogs who had nothing but swimming and ball playing on their minds, and constantly disturbing the flutterbys – I was never able to count more than six simultaneously, there may have been as many as a dozen.  There was fluttering blue everywhere, and of course, when they sit down, they pretty much disappear.

   Jeremy Tatum writes:  I went to Munn Road today, to Pike Lake substation and nearby.  I, too, saw lots of mud-puddling Western Spring Azures, mostly near to the yellow gate, I also saw one Sara Orangetip and one Western Brown Elfin there.  The vegetation of huge parts of that area has been flailed down, so that the area now looks like an ugly industrial wasteland.  Presumably it has been done to ease access to the electricity pylons, and the vegetation, in time, will grow back.  I hope no permanent destruction is in progress.

 

  The California Tortoiseshell that has been reported off and on from the Mount Tolmie reservoir since April 19 was still there at 4:30 this afternoon.

 

  Marie O;Shaughnessy sends a photograph of a Mourning Cloak that she saw along the lower trail at Mount Douglas, April 10th.

   Jeff Gaskin and Kirsten Mills saw a California Tortoiseshell at 4:00 pm on the Mount Tolmie reservoir today, as well as three Cabbage Whites elsewhere on the hill.  The tortoiseshell was presumably the same individual that Val George photographed on April 19.  However, Val photographed another California Tortoiseshell today on the summit of Mount Douglas.

    Aziza Cooper puts me a little on the spot!  She writes that she saw some commas on the tracks near the Goldstream campground, and she wants to know what species they are.  Well may you ask, Aziza, and you are just as good (or bad) at these things as I am!

Well, I (Jeremy Tatum) shall put a label under the photographs, and if anyone disagrees with them (or even if you agree), please do let us know!  Aziza also saw a Sara Orangetip and a Cabbage White there.

   Jeremy Tatum saw only his second butterfly of the year today – a Western Spring Azure at Blinkhorn Lake.  He comments that after a dull winter, he had forgotten how very beautiful these butterflies are.

 

 

   On April 20, Nathan Fisk found a bee holding fast to a Flower of Deltoid Balsamroot.  Thank you Sean McCann for identifying the bee as a kleptoparasitic bee of the genus Nomada.

   Gordon Hart writes:  I visited Francis/King Park yesterday and saw one Sara Orangetip Anthocharis sara, and a Propertius Duskywing Erynnis propertius. There were also several Mesoleuca gratulata flying. This was in the area across the road from the Nature House. At home in the Highlands, a Green Comma flew by, but I saw no other butterflies.

A bee fly photographed by Aziza Cooper at Trail Way, Goldstream Heights, April 19.  Keep a look out for these flies shooting their eggs into the burrows of mining bees.  And welcome back, Aziza.

   And a bee fly photographed by Gordon Hart at Prospect Lake Road.  Although there are many species of bombyliid, according to the website https://bugguide.net/node/view/14997  Bombylius major is the only Nearctic Bombylius species with the wing pattern shown by Aziza’s and Gordon’s flies.  So, although the piles are different colours in these two individuals, I shall label them both Bombylius major.  Any comments by knowledgeable dipterists would be welcome.

   Mistakes:

 

        Jeremy Tatum writes:  Every now and again I make a mistake while typing out the day’s posting for Invertebrate Alert. Maybe it’s something big;  maybe it’s just a small spelling or even punctuation mistake.  My friends are so polite and don’t wish to offend me that they do not mention it.  Fear not!  Far from being offended, I will be very happy and pleased to be notified of mistakes, so that I can correct them as soon as possible.  Otherwise the mistake remains there forever on display, under my name, for all to stare at!   So please do let me know of any that you find.  jtatum at uvic dot ca    Thank you!

On April 18, we posted pictures of some early bees on or around some Shooting Star flowers, which we labelled Dodecatheon.  Apparently the botanical taxonomists are every bit as enthusiastic about name changes as are the zoologists, and Jeremy Gatten points out to me that Shooting Stars are now supposed to be in the genus Primula. Jeremy Gatten confesses to being a bit baffled by this – as does Jeremy Tatum – though we have to assume that the taxonomists have some good reason for it.  To my eyes, Shooting Stars bear little resemblance to the Primroses that I used to see in my youth in the hedgerows of England in spring.
