     Mike Yip writes from Nanoose:  Great day for golf at Fairwinds (April 25), and it was even more enjoyable to find a Western Pine Elfin basking on the 3rd green and a Grey Hairstreak on the 18th green. After golf I checked Cross Road and found an obliging Western Spring Azure.

   Jeremy Tatum writes:  I photographed a weevil, on Rumex crispus at Rithet’s Bog on April 24.  Identification proved a bit of a problem and it needed a combined effort from three beetle enthusiasts.  Charlene Woods identified it as a species of Lixus, but she pointed out that there were only two species of Lixus on the British Columbia list, and Scott Gilmore didn’t think it was either of these.  Finally Bob Anderson identified it as Lixus concavus – a widespread species in North America, but which somehow had managed to avoid being on the British Columbia list.  An exciting experience, and thanks to the three people who went to a lot of trouble to identify it.

   Here’s a photograph of a bee fly Bombyliu major from Ken Vaughan in the Highlands:

   Syrphine flies and chrysomelid beetles are notoriously difficult to identify from photographs, and Ken has a photograph of one of each from the Highlands.  We are very grateful to Jeff Skevington (flies) and Scott Gilmore (beetles) for giving it their best shot.

 

    First, the fly.  Dr Skevington writes:   It looks like Eupeodes but I hesitate to put even generic identifications on syrphines with only one view.

 

Possibly Eupeodes  (Dip.: Syrphidae – Syrphinae)  Ken Vaughan

 

   Now the beetle.  Scott Gilmore writes:  Leaf beetles are hard even with a specimen in hand. This appears to be from the tribe Alticini and I think (guess?) genus Altica.
