More photographs by Ian Cooper from Colquitz River Park and the Galloping Goose Trail in View Royal yesterday morning, March 18. We start off with an extraordinary wingless hymenopteran kindly identified for us by Claudia Copley as Polyaulon canadensis. Jeremy Tatum writes: I know nothing about the natural history of this unusual insect, although it is classified in the Family Ichneumonidae, most (all?) of whose members are parasitoidal on other invertebrates.

Ian writes: I finally got to see the mature resident trapdoor spider of the large burrow entrance spotted some days ago that I was so excited about.

Rosemary Jorna sends photographs of a bumble bee from her Kemp Lake area garden, March 18. We are grateful to Gordon Hart, who, while pleading that he is not an expert, answered our request to have a go at identification. He comes up with probably Bombus sitkensis

Ian Cooper writes: Here are some pre-dawn photos from Colquitz River Park and the Galloping Goose trail 9km site, March 16 2021. It got quite chilly that night.

Ian writes: This larva appeared to be feeding on rust-colored lichen growing between the small cracks and crevices in the tree’s bark. It was tiny. Maybe 6 mm. The bristles on its head look as though they are dusted with what I assume are lichen spores. Later: Jeremy Tatum writes: This larva was finally identified (see March 26) by Dr David Wagner, Charlene Wood and by Ian himself, as the larva of a soldier beetle (Cantharidae).

Butterfly! Jeff Gaskin reports that Kirsten Mills saw a Cabbage White in Brentwood Bay on March 16. There have been two previous reports (February 9 and March 5) of Cabbage Whites this year – both premature emergences, one in a kitchen and one in a greenhouse. Depending on what you think “counts”, this may be the first butterfly that “counts” this year! Invert Alert merely records the occurrence.
