    Last month Jochen Möhr subnitted some pictures of a spider from his home in Metchosin.  Dr Robb Bennett writes:  These are nice images. It would be nice if there were some indication of the size of the spiders.   However I’m pretty sure they are Parasteatoda tepidariorum. A cosmopolitan house spider – I usually see them under window sills or eaves where they have their retreats. Their prey capture webs are long sticky silk strands that extend down to the ground. They are quite efficient – I have seen lots of giant house spiders and big beetles in their webs and have heard reports of them even capturing European Wall Lizards.  

 

   Jeremy Tatum adds:  According to Web entries they can also inflict a fairly severe bite.  One site says severe pain for 16 hours.   I don’t know if this happens very often, but I thought I should mention it so that viewers can be suitably circumspect if they come across this spider.

  Mike Yip writes from Nanoose Bay:  Scores of Woodland Skippers in the garden with the occasional Pine White and Cabbage White.   A few Common Woodnymphs flying by but no nectaring or basking.

   A rare full upperside view, showing that the Branded Skipper is by no means the only skipper whose male is conspicuously “branded” with androconial scales, which release male hormones to advertise his presence.

   Jeremy Tatum shows a White-lined Hawk Moth, which came from the caterpillar shown on July 15 and the pupa shown on July 25.  The caterpillar was found at McIntyre reservoir, which is where I released the moth today.  Larval foodplant – Epilobium.

   On July 2 morning, we posted a photograph of a syrphid fly, but I didn’t know who the photographer was.  Will anyone admit to photographing  it?  In any case I’m happy to say that we now have an identification for the fly if not for the photographer.  Thanks to Michelle Locke for identifying it as Dasysyrphus intrudens, which she describes as “a complex of species, yet to be sorted out”.

   Jeremy Tatum shows a photograph of a female caterpillar of the Vapourer Moth (also known as the Rusty Tussock Moth) from English Hawthorn at Quick’s Bottom.
