   Yesterday Rosemary Jorna photographed a snakefly on Peden Bluff.  At one time snakeflies were included in the Order Neuroptera, but these days they have their own Order, Raphidioptera, and in our area they are distributed among several genera in two Families.  I haven’t yet learned how to identify them (writes Jeremy Tatum), although I think the one Rosemary photographed may be a species of Agulla  in the Family Raphidiidae.  If any viewer can help us with this, please let us know.

   Jeremy Tatum sends a photograph of a striking moth from his Saanich apartment building this morning.  He writes:  I didn’t recognize it as being a colour variety of the same species  – Sabulodes aegrotata – as Jochen’s moth shown on April 16.  Thanks to Libby Avis for setting me straight!

   Jeremy Tatum writes that the two California Tortoiseshells that have been on the Mount Tolmie reservoir for several days were still there at 5:30 pm on April 17.  They are best seen in the late afternoon or early evenung.

 

   Jeremy Tatum continues:  On April 4 we showed a photograph of some newly-hatched caterpillars of the Sheep Moth.  Here are these same caterpillars today:

 

Sheep Moth Hemileuca eglanterina (Lep.: Saturniiidae) Jeremy Tatum

   I don’t know how the moth acquired its name “Sheep Moth” .  (Ideas, anyone?)  I have occasionally seen it called the “Elegant” Sheep Moth, although the recent addition of this adjective is quite inappropriate.  The “eglanterina”  in its scientific name does not mean “elegant” or anything like it.  It refers to one of the frequent foodplants of the caterpillar, namely the Sweet Brier Rose Rosa eglanteria, the word “eglanteria” meaning “spiny”, referring to the prickles on the plant.  The Sweet Brier Rose is also known as the Eglantine Rose, so those who would like an adjective before “Sheep” should perhaps call the moth the Eglantine Sheep Moth, rather than the Elegant Sheep moth.

 

Marie O’Shaughnessy writes:  I saw this beauty on Mount Douglas on the 16th April around 2- 3pm. All rather hot up there at that time. Seen near the top parking lot.
