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.

   Jochen Möhr writes from Metchosin:  This morning finally!  After a night with 7 °C, three Egira hiemalis at the wall.

Jeremy Tatum writes:  “Lepidoptera” means “scale wings” – and you can see why from this photo!

 

Here are some more small creatures from the Galloping Goose Trail photographed by Ian Cooper.  First a small (4 mm) spider – two images of the same individual:

   Next, two (different) harvestmen:

  We have not been able to identify the spider or harvestmen above.  We have not been able to identify the Order of the creature below, though we believe it to be the larva of some sort of fly (Diptera). If anyone can help, please do so!

   More springtails from Ian Cooper, kindly identified for us by Dr Frans Janssens.   Most of us rarely see these tiny animals, so it is quite an education to see them so close up.

   And here are two spiders.   Among the numerous small creatures we come across, we cannot always identify every one, and we’ll have to settle with admiring and appreciating these two without necessarily being able to attach a label to them.

   Rosemary  Jorna photographed this gnat on a maple in her Kemp Lake garden.  I am not expert enough, writes Jeremy Tatum, to make an identification, but I think it is probably either a limoniine tipulid (a sort of small crane fly) or a trichocerid (winter gnat).

 

Dip.: probably Tipulidae – Limoniinae,  or Trichoceridae  Rosemary Jorna

 

   Caterpillars are easier for me to identify.  This one, on Indian Plum, is Paraseptis adnixa first shown as a very young caterpillar on February 8, now almost full grown, perhaps one more instar to go.

   Jeremy Tatum writes:  Here is one of a number of commensal creatures that share my table (Latin mensa, a table) with me – or at least share my apartment building in Saanich if not my actual table.

   Ian Cooper sends an unusual photograph of a harvestman on snow, Colquitz River Park, February 17.   Dr Philip Bragg writes:  I have not seen a harvestman on snow before. I notice that it is keeping its body well away from the snow on its long legs. The photo is not clear enough for a positive identification but I think that it is Platybunus triangularis.

  Rosemary Jorna, sends photographs of spider engaged in Anglo-Saxon attitudes in her Kemp Lake basement, February 17.   Dr Robb Bennett writes:

 

Hmm, not your usual indoor trashy theridiid. It’s a linyphiine linyphiid – always have trouble eyeballing them based on colour patterns: probably either a Neriene or Microlinyphia but I really don’t know.
