  Here are some invertebrates photographed by Ian Cooper in *Colquitz River Park in Saanich and by the 9 km marker on the Galloping Goose Trail in #View Royal early on Feb 7 2024.   Ian’s suggested identifications are given.

Invertebrate Alert has not often had photographs of earthworms – although they are certainly invertebrates!  The default species found in gardens is usually Lumbricus terrestris – the one we all learned about in biology lessons at school!  But this one was not in a garden, and Ian suggests that it might be a native species – Arctiostrotus vancouverensis.  If there are any earthworm specialists among our viewers, please let us know what you think!

Val George writes:  This morning, February 11, this moth, Phigalia plumogeraria, was on the wall of my Oak Bay house, along with two Hydriomena nubilofasciata.
