   The West Coast form of the following spectacular hawk moth is treated by some authorities as a separate species Smerinthus ophthalmica.  Here, for better or worse, I retain the name Smerinthus cerisyi.

  On the butterfly front, Gordon Hart, just back from a visit to Ontario, reports that he has Cedar Hairstreaks, Western Spring Azures, Green Comma and Pale Tiger Swallowtails in his Highlands yard.

 

   Ron Flower sends photographs of a Silvery Blue from the Colwood turn-off, and a Satyr Comma from Goldstream Park, May 17.  Satyr Commas, formerly common, have become quite rare in  the last two years, so it is reassuring to know that there are still a few about.

   Jeremy Tatum writes:  From Tuesday until Saturday inclusive this week I shall be heavily involved with the Canadian Astronomical Society meeting in Victoria.  Consequently there may be some delays in posting Invert Alert contributions.  By all means continue to submit your observations and photographs, though it would be helpful if photographers would, during these few days, concentrate their attention on the less frequently photographed species.  Thank you.

 

   Erratum:  In the posting of May 20 evening, I had incorrectly labelled a snakefly.  This has now been corrected.

 

    On May 19 Andrew Simon photographed a jumping spider on Galiano Island.  We are thankful to Sean McCann for confirming its identification as Metaphidippus manni.

   Andrew Simon and Scott and Sable Gilmore, while conducting a mini bioblitz on Galiano Island yesterday, came across two snakeflies.  We are grateful to Chris Ratzlaff of the Spencer Entomological Museum for identifying them as Agulla assimilis.  Dr Ratzlaff remarks: “The pale scape (instead of black) and the long pterostigma are key characteristics of this species. Second most common in BC (first is adnixa)”

The one with the long ovipositor is a female.   The other is a male.
