    Mike Yip sends a photograph of a grasshopper from Nanoose.  He writes:  “When I first saw this creature flying by I thought it might be a moth. It had black wings with a yellow border and finally landed about 50 m away. When I finally got a clear view it turned out to be a grasshopper.” 

  This is the Carolina Grasshopper, often known colloquially as the Mourning Cloak Grasshopper, since it can be mistaken in flight for that butterfly.

 Corrigendum.  On September 23 evening we posted a photograph by Gordon Hart of a grasshopper, which we labelled Trimerotropis verruculata.  James Miskelly pointed out that it is more likely to be  T. fontana.  Gordon went through his photographs of the same individual and he found one that showed its bright blue tibia, showing that it is indeed fontana. We are grateful to James for spotting the mistake.  We have corrected the September 23 caption, and we show the new photograph below.

    Jeremy Tatum writes:  It is remarkable how common Thera juniperata is this year.  There were two at the door of my Saanich apartment this morning, and two at Jochen Möhr’s house in Metchosin.  Jochen also had two Epirrita autumnata.

   Yesterday night, Ian Copper photographed two weevils along the Galloping Goose trail in View Royal.  Thanks to Scott Gilmore for identifying them for us.  Romualdius scaber is quite tiny – estimated about 3 mm.
