   Mike Yip sends a photograph of a caterpillar found under an apple tree in his Nanoose garden.  We don’t know exactly what it is, but Dr David Wagner suggests that it may be a morph of a species of Zale

Possibly Zale sp. (Lep.: Erebidae – Erebinae)  Mike Yip

    Jochen Möhr sends a photograph of a moth and a gigantic beetle from Metchosin.  Thanks to Libby Avis for identifying the moth.

There was a young man from Tralee

Who was stung on the nose by a wasp.

When asked:  “Does it hurt?”

He replied: “No it doesn’t –

It’s a good thing it wasn’t a hornet.”

Sometimes attributed to W.S. Gilbert

   Val George writes:  Yesterday afternoon, August 2, there were many dragonflies at McIntyre Reservoir: Eight-spotted Skimmers, Blue-eyed Darners, Blue Dashers and two female Western Pondhawks (photo of one of them). [Jeremy Tatum interjects – I was there too on that day, and I also saw a Black Saddlebags – but almost no butterflies, in spite of the Teasels being in full bloom.]   Val continues:  On the way home I checked the door of the Nature House at Swan Lake; as well as several Malacosoma moths there was this large Catocala moth.

   Jeremy Tatum writes:  In spite of being so large and spectacular, Catocala moths are notoriously difficult to identify to species.    For Val’s moth, I am very tentatively thinking of C. unijuga but this is by no means certain.
