   Val George writes:  This morning, July 14, the VNHS birding group found this Sheep Moth caterpillar, Hemileuca eglanterina, in Uplands Park in Oak Bay.   Jeremy Tatum remarks:  This caterpillar should be handled (if at all) with care.  Some people (including myself) find that the caterpillar may give them a rash.

   Mike Yip writes from Nanoose Bay:  A bunch of these slimy looking larvae have been defoliating my wife’s quince tree. They are about 8 – 9 mm and haven’t bothered any of the apple or pear trees. Any idea what they are?   Jeremy Tatum replies: They are the larvae of a sawfly Eriocampoides limacina, also known as Caliroa cerasi.  They are often to be found on cherry trees.  I wouldn’t altogether trust them with apple or pear.  “Limacina” means “slug-lke”.  “Cerasi” means “of the cherry”.

   Jeremy Tatum writes that last night (July 10) at 7:00 pm there were two Painted Ladies and a Red Admiral flying erratically at the top of Christmas Hill, doubtless because of the strong smell of marijuana there.

 

   Marie O’Shaughnessy writes: There seem to be plenty of Lorquin’s Admirals along with Cabbage Whites and Western Tiger Swallowtails, especially in the Oak Bay area, with continuing dry and hot conditions. Lovely to see so many butterflies these days.

   Here is an interesting upperside-and-underside photograph of a tortricid photographed by Bryan Gates.  It needs dissection to be absolutely sure of the identification, but we are grateful to Jason Dombrowskie for identifying it (with this caution) as probably Pandemis cerasana.

   Rosemary Jorna writes:  Another sighting, this time from Kemp Lake. A swallowtail butterfly was moving oddly on my neighbour’s lawn, When I looked closely it was obviously dead and this wasp was butchering it (July 10, 2018, Kemp Lake area).   It made several trips as the corpse was drifting round the yard in the wind.  This was the best shot I got in tracking it on and off for about half an hour. Then the butterfly disappeared, probably blown away as the wind picked up
