 Noctua pronuba caterpillar (Lep.: Noctuidae) with a Deroceras invadens– (Pul.: Agriolimacidae)

This was a bizarre sight: The slug had evidently climbed up the caterpillar’s back and appeared to be interested in nibbling its head.  Very strange!

   In case you missed Dr Bennett’s talk on spiders this evening, there is to be another spider talk next week by another of our local spider experts – Claudia Copley.  Claudia’s talk is organized by a new UVic student insect club by the name of CICADA, with which we expect to maintain close contact.   CICADA assures us that all will be welcome.   (ECS = Engineering and Computer Science)

 

 

Jeff Gaskin writes:   Today, October 23rd, I saw a nice fresh Red Admiral at the top of Christmas Hill at 2:20 p.m today.  Also, there was the Painted Lady which may be the same one I saw here on October 12th and 13th.  I did a short walk in the Burnside/Gorge community but didn’t find any Cabbage Whites.

Val George sends this photograph of Xanthorhoe defensaria, the wall of his Oak Bay house this morning, October 22.   Jeremy Tatum writes:  This looks like an unsual variety to me, but apparently it is well within the range of variability of this species.  Compare with a more typical specimen shown in Val’s September 17 morning photograph.

Jeff Gaskin writes:  On October 21st, I found 4 Cabbage Whites.  One was in Cuthbert Holmes Park where I also saw 2 Darners, I believe they were probably both Paddle-tailed Darners. The other 3 Cabbage Whites were seen in the Burnside/Gorge community.
