   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).

   Jeff Gaskin  saw a nymphalid butterfly today at Esquimalt Lagoon by Lagoon Road and Ocean Boulevard.  He had only a fleeting glimpse – not enough to identify it – but he thought maybe Red Admiral.

   Cheryl Hoyle writes:  I was driving on Goldstream Avenue last night and this beetle landed on my windshield.  I was wondering if it is a Predacious diving beetle Dytiscus sp.   Charlene Wood says yes it is!

    Jeremy Tatum remarks:   We have had very few aquatic insects on this site so far.  Photographers, let’s think about that next Spring!

   Mr E sends a photograph of a Stonefly on a coffee cup at Goldstream Park, November 3.  Jeremy Tatum writes:  Stoneflies are regretfully under-represented in Invertebrate Alert, there having been only two (in 2014 and 2016) shown before since the site started in 2010.  They are common in Goldstream Park, and deserve more attention from photographers.  I wonder ifany viewer can identify this individual, even if only to Family level.

   Jeremy Tatum writes:  I shall dutifully label the photograph below Erannis vancouverensis, although I don’t know the difference between it and E. defoliaria.

   Jochen Möhr writes from Metchosin this morning:  This morning, there are 1 Epirrita autumnata and 3 Sunira decipiens.   I am intrigued by the subtle variations in the pattern of E. autumnata.  Hence I attach the picture.
