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 (jtatum@uvic.ca). 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.

   Ian Cooper cycles along the Galloping Goose trail, which is covered with hard-packed snow and ice, alone at night, and gets down his hands and knees to photograph all sorts of unfamiliar invertebrates.  Pretty risky – but he gets some interesting results.  How many of us, I wonder, have seen the animal below, or know what it is?  It’s a springtail – a group formerly in an Order Collembola, but now considered to comprise several Orders within a Subclass Collembola of the Class Entognatha.  (Not an insect.)  The one in the next two photographs (two different individuals, same species) is in the Order Entomobryomorpha.

   The globose springtails are perhaps more familiar (if they are familiar at all!), and belong to the Order  Symphypleona.  The one below is in the genus Ptenothrix, but Collembola expert Frans Janssens tells us that this one is a new, undescribed species!

   Libby Avis sends a photograph of Egira hiemalis from Port Alberni, February 6, her earliest date for the species there.   This is often the first noctuid to appear in the year, often appearing in February or even January.   The earliest recorded by Invertebrate Alert  was  January 16, in Victoria, 2014.

   Jeremy Tatum writes:  Here is a Ctenolepisma longicaudata from my Saanich apartment.   This is a three-pronged bristletail – but this individual seems to have lost one of its prongs.

     Jeremy Tatum writes:  The moth shown below emerged today from a pupa formed from a caterpillar last year.  Fortunately it just missed the cold weather – today is much warmer and the snow is melting. Identifying the moth was a bit tricky, but Libby Avis and I both came up with Orthosia praeses.  The reddish brown head gave it away.

   Undeterred by the cold weather, Ian Cooper was still hard at it with his camera last night near the 9 km marker on the Galloping Goose trail, when he discovered a pseudoscorpion also braving the cold.

   Jochen Möhr found this caterpillar emerging out of some corn salad that he had harvested for dinner.
