   Scott Gilmore photographed this springtail, Isotoma viridis, from his backyard in Lantzville yesterday (March 16).  Frans Janssens confirmed the identity of the beast.

   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.

 

Drone Fly Eristalis tenax (Dip.: Syrphidae)  Ian Cooper

   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.

   Ian Cooper continues to show us the remarkable range of unfamiliar creatures that he is finding at night along the Galloping Goose Trail and Colquitz Creek Park.  Thanks to Drs Robb Bennett and Frans Janssens for a huge amount of help with the spiders (Robb) and springtails (Frans).

 


 Female Clubiona lutescens (Ara.: Clubionidae) Ian Cooper

   In  describing his encounters with trapdoor spiders, Ian writes:  After visiting Colquitz River Park, I went to the GG 9km observation site before dawn today (March 14) and was pleasantly surprised to spot multiple resident trapdoor spiders of various sizes ‘on duty’ at their burrow entrances along the embankment by the trail, including some very tiny ones. The newly discovered larger spiders generally retreated into their lairs as my light and camera got too close for comfort, so it was hard to get a good close up shot of them. One of the smaller spiders slammed its folding doors in my face when it suddenly withdrew. Shocking and rude, but cute to see!

   Ian continues:  I also spotted a Jumping Bristletail for only the second time.  I was lucky to see it, as its grey coloring made it barely visible against the tree bark it was on.

The remaining animals below are all springtails from various Families – some would say various Orders.
