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 Möhr sends a photograph of a geometrid moth from Metchosin.  We have previously labelled this moth Venusia obsoleta/pearsalli, because we have been unable to distinguish between these two similar species.   Somewhat unexpectedly, Venusia obsoleta  has now been moved to another genus, and is now Nomenia obsoleta.  We are now in the difficult position that we cannot distinguish between two moths in different genera.  A further complication is that a third species, N. duodecimlieata is also a possibility,

According to MPG, male Venusia pearsalli have filiform (simple) antennae.  Unfortunately it does not say what the female antennae are like, nor do we know the sex of Jochen’s specimen, and we don’t see quite enough of the antennae to be sure what form they are.  MPG says the antennae (it doesn’t specify which sex) of Nomenia obsoleta are “apparently” unipectinate.

   Jeremy Tatum sends a photograph of this woodling moth that flew into his living room in Saanich last night.   Moths of the genus Egira are known as “woodling”moths.  They are largely western moths, and they are among the first noctuid moths to be seen in Spring.  Egira hiemalis is the earliest, usually appearing in February.  E. curialis (below) and others follow later.

   Happy Nowruz, everyone!

Now that Spring is here, insects are starting to stir, although this syrphid fly photographed yesterday by Aziza Cooper seems to have had a chilly night, for it is covered with dew.

Jochen Möhr was wondering why we seem to have more butterflies here in suburban Victoria than he sees in the wilds of Metchosin.  We are glad to hear, therefore, that on March 19 Jochen at last saw his first Mourning Cloak of the year on William Head Road.  Unfortunately much too briefly even to attempt to photograph it.  Jeremy Tatum writes:  Well, I haven’t seen a Mourning Cloak yet this year – so Metchosin can’t be all that bad!

Spring starts at 10:06 pm PDT this evening.

Aziza photographed this Mourning Cloak on the Mount Tolmie reservoir on March 18.

   Aziza writes:  Today, March 19, I saw three Mourning Cloaks – one along the Colquitz Creek path near Marigold Street, one flushed from Conway Road near Interurban Road, and one at the Beaver Lake Riding Ring trails (photograph of this one below).  Two California Tortoiseshells were still on the Mount Tolmie reservoir at 5:30 pm.
