Ian Cooper writes:  Here are some of the photos taken at dusk by the Galloping Goose trail on June 30 2024.

The next two photographs show a gracillariid moth of the genus Caloptilia.   Jeremy Tatum writes:  Although I have not been able to determine the species, it does seem to bear a close resemblance to the very appropriately named Caloptilia nondeterminata, which is most likely what it is.

Here are two photographs by Aziza Cooper of the Milbert’s Tortoiseshell reported by Aziza from Swan Lake on the June 30 afternoon posting.

And today, July 2, Aziza writes:  At Maber Flats there was a Milbert’s Tortoiseshell next to the road. Another butterfly flew past, possibly a second Milbert’s. There was also one Cabbage White.

Jeremy Tatum writes:  I tried to persuade Dr Rob Cannings not to spend a lot of his time in the difficult task of tying to identify a dragonfly exuvia, but he gave us a good chunk of his time anyway.  Dr Cannings writes of the exuvia below:  It looks like Libellulidae, but the exuviae of some Corduliidae can be very similar. The structure of the labium is important and can’t be seen well here, except to separate these families from others. The shape of the head in exact dorsal view is useful as are the size/presence/absence of lateral and dorsal spines – especially in identifying genera and species. But you have to have awfully good views of these characters, and photographs usually are not clear enough.

And, by the way, Latin scholars, we do know that the word “exuviae”  is not used in the singular in classical Latin, but we badly need a word to describe cast skins such as the ones above, so entomologists have agreed to call such a skin an exuvia, which we hope will not cause undue damage or inconvenience to anyone.  “Exuviae” means “spoils” (e.g. of war); the English word, like the Latin, is not generally used in the singular, either.

Although there is a Seven-spotted Lady Beetle in the background at the bottom
of the photograph,  the larva on the flower is that of Harmonia axyridis

 

The photograph below shows two crane flies apparently in copula, but there seems to have been an accident and one of them died (a long time ago) and remains attached.

Colias alert!  Ron Flower writes:  Today, Sunday June 30, we spent half an hour chasing a sulphur butterfly around McIntyre Pond and fields.  Probably an Orange Sulphur but could not get a pic. It’s the earliest I have seen one.

Milbert alert!  Aziza Cooper writes:  Today, June 30, there was one Milbert’s Tortoiseshell at Swan Lake along the path near Saanich Road.  Photographs were obtained, which we hope can be shown in the next posting.  There were also five  Essex Skippers and one Western Tiger Swallowtail.

Jochen Möhr sends a photograph from Metchosin of a White Satin Moth, unfortunately out of the reach of the tripod mounted camera.
