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.

   Annie Pang reports seeing another Cedar Hairstreak (a different individual from the one shown yesterday) at Gorge Park this morning.

 

   Nathan Fisk found this bug in Mill Hill Regional Park on May 3.  Thanks to Thomas Barbin for identifying it as a stilt bug of the Family Berytidae.  Thomas points out that it bears a close resemblance to the species Neoneides muticus.  However, Berytidae is a large family of somewhat similar insects, and it seems safest to leave this one at Family level.

   Message from Gordon Hart – May Butterfly Walk

 

Hello Butterfly Watchers,

Our second walk of the year will be this Sunday, May 6. We meet at the top of Mount Tolmie, by the reservoir, at 1.00 p.m. You can park in the parking lot there, or in the large lot north of the summit. After a look around the summit, and depending on the weather, we will decide on a destination from there. 

See you on Sunday,

Gordon Hart

Victoria Natural History Society

 

 

Jeremy Tatum adds:  As Gordon points out, as usual we decide on a destination when we meet on Mount Tolmie – so give it a moment’s thought, and if you have any suggestions, don’t be shy about sharing them when we meet!

   Apparently we don’t have to go out into the wilderness to see butterflies.  This morning’s posting showed a Western Brown Elfin near the Royal Jubilee Hospital.  Now Annie Pang comes up with an unexpectedly early Cedar Hairstreak in Gorge Park yesterday, May 2.  A “lifer” for Annie!

   Jeremy Tatum writes that at 6:15 pm this evening (May 3) there were two California Tortoiseshells and a Red Admiral on the Mount Tolmie reservoir.  So now is the time to look for hilltopping nymphalids there in the late afternoons and early evenings.  The action has started.

 

   Jochen Moehr had a good night two nights ago with his moth trap in Metchosin.   He and Jeremy Tatum are exceedingly grateful to Libby Avis for the identifications – this saves us a huge amount of work.  Jeremy writes:  No one seems to know how to distinguish reliably from photographs between Venusia obsoleta and V. pearsalli so I have written both species names under the photographs.  Egira simplex/crucialis is another difficult pair, though Libby and I both lean towards simplex in Jochen’s photograph below. Libby said she wasn’t 100 percent certain about Apamea cinefacta, though I think she’s almost certainly right, and that’s how I’m going to label it!

    Val George and Jeremy Tatum met briefly at about 4:30 yesterday (May 2) afternoon at  the Mount Tolmie reservoir, where we saw the California Tortoiseshell basking on the concrete at the same place where is has been seen since April 19.  And a Sara Orangetip flew by.

 

    Samantha Hatfield sends a photograph of a Western Brown Elfin – near her house not far from the Royal Jubilee Hospital.  Nice to see a butterfly like this in such an urban area.  Also a caterpillar of the Silver-spotted Tiger Moth.

   Nathan Fisk writes that he had such a lovely visit with two of these gems (Silvery Blues) at the Colwood turn-off lupine patch. The lupines are maybe about a week from flowering, maybe sooner if the sun continues.

   Jochen Moehr writes: Today, with the sun blazing down on our slope in Metchosin, there was a lot of butterfly activity.  Quite a few Western Spring Azures.  I saw up to four simultaneously, and they were around all the time.  Also one Grey Hairstreak, and one Sara Orangetip which I saw four or five times, always as a single butterfly.

   Cheryl Hoyle sends a photograph of bunch of caterpillars of the Sheep Moth from Uplands Park, April 30.  These caterpillars may give a mild (or not-so-mild) rash if handled.  I couldn’t think of a suitable collective noun for a bunch of gregarious caterpillars, so I just used “bunch”.  Suggestions welcome.  Their usual foodplants are either Ocean Spray or Snowberry.

Today at the top of Mount Douglas we got our first swallowtail of the year – an Anise Swallowtail.

Also at the top were two Sara Orangetips and one Western Spring Azure.
