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.

   Jeremy Tatum writes:  Here are two more of the difficult challenges that Mr E has set us.  The first is a leaf beetle of the Family Chrysomelidae.   This is a huge Family, so it is difficult to get an exact identification.  However, Scott Gilmore had a go and he believes it is a beetle in the genus  Altica.

  Jeremy continues:  At first I had no idea what the creature below was, but now I believe it is a non-biting midge of the enormous Family Chironomidae.

   Mr E has been photographing all sorts of invertebrates that are going to be a challenge to identify.  We’ll start with two slugs from Prospect Lake.  Jeremy Tatum writes:  The first one doesn’t have the usual colour and pattern of a Banana Slug, but I can’t think of any other slug that looks like this one, so for time being I’ll label it as a probable Banana Slug Ariolimax columbianus.  I just don’t know what the second one is.  If any viewer has ideas on either of these slugs, please do let us know.

   Next a small spider.  Dr Robb Bennett writes that he “thinks” it is Enoplognatha ovata.  If that’s what Dr Bennett “thinks” it is, that will be pretty close to certain!

   Cheryl Hoyle writes:  I took these photographs on November 6th in my home in View Royal.  Maybe Steatoda grossa?

 

   Jeremy Tatum writes: Yes, I think so; but I noticed that the pattern on the back is much more pronounced than on other photographs that we have had of this species, so I asked Dr Robb Bennett to comment.  He writes:  Yes, Cheryl is correct: a juvenile Steatoda grossa.   Juveniles (and mature males) have lots of abdominal patterning, as in the images. The patterning largely disappears in the females by the time they reach maturity (males retain most of the juvenile pattern).
