   Mike McGrenere writes:  Daniel Dönnecke and I hiked up Mount Douglas today looking for birds and butterflies. The butterflies were the highlight, though. We saw two California Tortoiseshells at the top (one by the teacup lookout and the other by the tower), 15 Sara Orangetips, 3 Spring Azures and 3 Propertius Duskywings. We also saw a Cabbage White along the Lochside trail.

   Annie Pang sends a series of photographs of the Western White Ribbon Carpet Moth Mesoleuca gratulata. It was busy laying eggs of the buds of the Himalayan Blackberry Rubus discolor. The moth inspired Annie to write an ode in its honour.




Ode to a White Ribbon Carpet Moth


                 Annie Pang


This tiny flitting, whimsy passing by;

is it a bit of petal or of cloth?

Too small to be a tiny butterfly,

by day, could it possibly be a moth?

I try to follow as it hovers near,

and looks as if quite soon it will alight

but then to my dismay, oh dear, oh dear,

it changes course!  Is off again in flight!


I chase it here and there, both up and down

and feeling hopeless that I’ll get a shot

do acrobatics, like a foolish clown,

not caring if I wreck my clothes or not.


And then she lands so neatly near my leg

and daintily she lays a tiny egg.

   Barbara McGrenere writes:  About 4:30 yesterday afternoon, Mike and I took a short hike to the south slope of Mount Douglas to look for butterflies.  There were eight Sara Orangetips –  one stopped briefly on a low growing plant with purple “pea” type flowers.  There was also one fast flying Propertius Duskywing and one Western Spring Azure that did not stop flying.

   Jeremy Tatum writes:  Today I saw a Sara Orangetip and a Propertius Duskywing on Christmas Hill, and two Satyr Commas along the Lochside trail between Lohbrunner’s and Blenkinsop Lake. I saw no butterflies at all on Mount Tolmie, but I did find something else of interest.  I came across a small colony of mining bees, probably Adrena sp.  There were about 20 burrow entrances on or beside the path, and several bees flying around them.  But almost as many as the bees were a number of bombyliid flies (Bee flies), probably Bombylius major, obviously interested in the burrows.  I got down on my hands and knees and watched them for a while, pretending to be J. H. Fabre.  Typically a fly would hover about a centimetre immediately above a burrow entrance, and then suddenly it would dart down to the entrance of the burrow in the twinkling of an eye, and be off.  I looked to see if there were any eggs scattered around the entrance to the burrow, but I couldn’t find any.  I watched this behaviour over and over again.  Although I can’t be a hundred percent certain, I believe that when a bee fly darted down in the twinkling of an eye, it probably threw an egg right down into the burrow.  It was fascinating to watch.  There were also a few very tiny bees with a shiny green thorax, which occasionally entered the burrow of the mining bees, and I was sure that this small bee was up to no good.

    Jeff Gaskin writes:   There was a Satyr Comma on Hector Road near Interurban Road around 11 a.m. Tuesday, April 7, and it looked in pretty good condition.


    Barbara McGrenere writes:  This afternoon, Mike and I had a Western Elfin basking on a rhododendron in our garden in Saanich.  It was cooperative and I have attached a photo.
