   Annie Pang sends a photograph of  Harmonia axyridis a species introduced from Asia into both North America and Europe, and now one of our most-often encountered ladybird beetles.  It has been given so many names that I (that’s Jeremy Tatum) have taken to calling it the “Many-named Ladybird Beetle”, although it is more often called the “Multi-coloured Asian Ladybird Beetle”.  The spotting is variable.  I usually recognize it by the black W on its thorax.

   Aziza Cooper writes: Yesterday, April 17, on Knockan Hill there were one Western Brown Elfin, two Spring Azures and one Cabbage White.

 

   In Beacon Hill Park on April 17 were one Mourning Cloak and one Cabbage White. At about 7pm on April 17, one Red Admiral was shivering in the wind on the reservoir at Mt Tolmie.

 

Today, April 18, at the railroad tracks just south of the bridge over Goldstream west of the Goldstream campground, there were about 30 Spring Azures, one Cedar Hairstreak and one Western Pine Elfin.

 

I observed up to 17 Spring Azures grouped together puddling in the mud between the tracks. The formerly flooded area is now only muddy.

 

  Wendy and Gerry Ansell write that they just had their first Western Tiger Swallowtail in their yard on Cordova Ridge – April 18th at 12:30 pm.

 

  Jeremy Tatum writes:  No butterflies on the Mount Tolmie reservoir on Monday (April 18) afternoon, but at about 6:30 p.m. there were two Red Admirals, one California Tortoiseshell  and a Green (I think!) Comma either on the reservoir or near the top of the steps.  The comma, in particular, seemed to enjoy resting on the Escallonia near the top of the steps.  If anyone sees it there, I’d be interested if you agree (or otherwise!) with the identification.

   Another Friendly Reminder.  Contributors please do try to remember that it is a huge help if you

 

     1. Send photographs as an attachment, not in the body of the message.

     2. Say where the animal was.  (Not “in my back yard” – I don’t know where your back yard is!)

     3. Say when you saw it.  (Not “yesterday”.  The date, please!

 

  Thank you all!

 

   Scott Gilmore sends from Lantzville photographs of a prominent moth and a ladybird beetle (the latter found by his son), both of which were lifers for him.  To the uninitiated, the moth may look like just another of the hordes of featureless grey or brown noctuids.  But to the enthusiast, it’s an exciting moth.  Not a noctuid at all, but a notodontid, an exciting family known as “prominents”.  The caterpillar of Gluphisia severa feeds on Populus.  The ladybird is the Two-spotted Ladybird.

   Rebecca Reader-Lee writes that on April 15 Emma found the spider shown below on the floor inside the house.  Robb Bennett tells us that it is either Coriarachne brunneipes, or Bassaniana utahensis.  He writes that they both pretty much look the same at the “whole spider” scale.

   Annie Pang sends a photograph of a bee fly, Bombylius sp.  This is a large genus, but the fly shown seems to resemble closely a female B. major.  They throw their eggs down the holes of mining bees.
