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.

   Rosemary Jorna found this snail at Kemp Lake Road, February 21.  It should be possible to identify the snail.  Suggestions, anyone?

 

Snail – for identification someone, please?    Rosemary Jorna

 

   Rosemary writes that, a metre from the live snail, she came across three shells close together all open in the same way.  She asks what would bring them to one spot and eat them in such a manner.  I wonder if they were broken by a crow or a gull dropping them from a height.  But then you wouldn’t expect to find three close together.  Ideas, anyone?  Identification of the snail, anyone?   It looks like a different species to me from the one above.  Jeremy Tatum

Jeremy Tatum writes:  Four items today, numbered  1,  2,  3, 4

 

There are two butterfly and other invertebrate related items in today’s (February 16) Times-Colonist.

 

1. I’ll type the first of them (page A3) in full.  I have not been involved in this and have no further knowledge of it, but it looks very interesting and it would be great if some of the viewers of this site became involved.  If any of you do, let us know how it goes!

 

The David Suzuki Foundation is recruiting volunteers to act as “butterfly rangers” in Victoria.  The Butterfly Project aims to increase habitat spaces for the winged insects in five Canadian cities. “We’re looking at creating patches of butterfly- and bee-friendly habitats,” said Lindsay Coulter, a green-living expert with the Foundation.

 

In Victoria, 20 to 25 volunteers will be selected for the training, then equipped with seeds.   The hope is that they will share the information with neighbours and other community members, Coulter said.

 

The local butterfly population is on the decline, she said, as a result of habitat loss.  But that can be stemmed by avoiding pesticides, replacing grass with pollinator-friendly plants, and taking other measures.

 

[Jeremy interjects here:  Re not using pesticides – refer to our posting for December 29.  The forestry people are going to be spraying for the mythical Gypsy Moth again this spring, targeting the Elk Lake area in particular.  While some of us are trying to protect butterflies by not using pesticides, others are trying to kill them by widespread spraying from aircraft.  Re replacing grass, etc., for more suitable habitat – fine, but do bear in mind that the caterpillars of all our satyrine butterflies and hesperiine skippers, as well many moths, feed on grasses.]

 

Newspaper article continues:

 

“We’ll be teaching people about our local situation in Victoria and what the needs are of the native butterfly species and the plants they require,” she said. For example, among the 70 native butterfly species on Vancouver Island, 10 prefer to lay their eggs on Ocean Spray and Stinging Nettle only, she said.

 

The Foundation is also hosting the project in Richmond, Toronto, Markham and Montreal.  The application deadline in February 19.  Applications are accepted at davidsuzuki.org/butterflyway

 

 

Training will take place March 4 and 5 at Goward House in Oak Bay.  Much of the work will take place in the fall, she said.  “Part of it is about increasing the local populations of different species, but even more so it’s about getting people out and connecting with their neighbourhoods and building social capital.

Coulter, who will lead the local training, said volunteers will have a curiosity and interest in supporting pollinators, as well as a willingness to reach out to their family, friends and colleagues.

 

 

  2.  Page D7 of today’s (February 16) Times-Colonist also carries an advertisement from the Butterfly Gardens at Brentwood Bay.  They are opening a new Insectorium on March 1, and the Grand Opening Week will be from March 1 to March 7, which will exhibit not just butterflies, but other insects and invertebrates from around the world.  Although viewers of this site may think of the Butterfly Gardens from a wide range of viewpoints, this will undoubtedly be interesting.

 

 

3.  I received an email (some of you may have received the same one) about bioblitzes.   There are to be three Parks Canada BioBlitzes this year:

 

1.  Fort Rodd Hill   May 13                          Aimee.Pelletier@pc.gc.ca

2.  Pacific Rim National Park    May 21      Diana.Lukinuk@pc.gc.ca

3.  Pender Island      June 10                         Athena.George@pc.gc.ca

 

 

There’s too much detail in the email for me to reproduce here,  but I think many of you know what a bioblitz is, and have participated in one or more before, or would like to participate in one of these, so I have given the contact persons’ addresses above.   Get in touch with them if you would like to participate.

 

 

4.   I have a few Clodius Parnassian ova that Devon Parker found last year, and I have started to keep a daily eye on them to see when they hatch.  When they do, I shall urgently need some Bleeding Heart Dicentra formosa.   Can anyone tell me where I may find some?  Preferably near UVic or my Poplar Avenue apartment, but when the eggs hatch I’ll need to get some Bleeding Heart immediately, no matter how far I have to drive.  I don’t need a general statement such as that it is a common and generally-distributed plant in the area, or there are probably some in such-and-such an area.  I’ll need an actual precise location where I can guarantee to find a few leaves for some Very Hungry Caterpillars.   Suggestions, anyone?   jtatum at uvic dot ca

   Jeremy Gatten reports the sighting of a Phigalia plumogeraria at Hans Helgesen Elementary School, Rocky Point Road, on February 13.  Phigalia plumogeraria is one of the earliest geometrid moths to appear in the year.  Reference to our Index shows that sightings in previous years for this species range from January 14 to March 14.  Like Operophtera and  Erannis, the flightless female has mere stubs for wings.  The male has large feathery bipectinate antennae to find her.

   Nathan Fisk writes (February 13):  With the Sun come the inverts! Only one buzzing around the daisies at Fort Rodd Hill. Looks a lot like the fly I saw in February last year but I’m no expert.  Jeremy Tatum responds:  Nor am I, but I’m certain that this is a drone fly Eristalis sp., and very close to certain that it is “the”  Drone Fly Eristalis tenax.

 

  Jeremy continues:  Yes, invertebrates are coming back, and I had two noctuid moths at my Saanich apartment this morning (February 14), both of them Egira hiemalis.  This is the first of our woodling moths to appear early in the year.  “Hiemalis” means “of the winter”.  I looked up in the Index to this site (click on INVERTEBRATE ALERT at the very top of the Invert Alert site to find the Index) and I see that Egira hiemalis has appeared on this site on dates ranging from January 21 to March 26.  I have never seen the caterpillar, but Bob Duncan gives the foodplant as Douglas Fir.

  Rosemary Jorna sends pictures of a harvestman from Kemp Lake Road, Otter Point, February 2.  Jeremy Tatum writes: I thought it looked a little different from the usual European Phalangium opilio, so I sent the photographs to Dr Philip Bragg of the University of British Columbia.  While he can’t be certain without seeing the actual specimen, he believes it is a native species of Leiobunum.

  There is to be a TV program on “The Wild World of Insects Inside Homes” on Channel Shaw 2 = Telus 100, at 8:00 pm on Thursday February 9.  This should be of interest to invertebrate enthusiasts.   You may have noticed a photograph of a spider on the front cover of this week’s TV Scene.  Robb Bennett tells me that the spider is possibly a species of Cheiracanthium (Eutichuridae), often common in homes, but more so in eastern Canada than here on the west coast.
