Jeremy Tatum writes: On September 6 Ian Cooper came across a white caterpillar with red spiracles hiding in a folded dead maple leaf on the ground along the Galloping Goose Trail in View Royal. Because it was half hidden in the dead leaf, it was impossible to get a perfect photograph without disturbing the caterpillar. Nevertheless, Ian got the photograph shown below.

Ian handed the caterpillar to me for rearing, and, before I could get any further photographs, the caterpillar had made a white silken cocoon. Just three days ago I had occasion to look inside the cocoon, and I discovered a pupa inside, white as the driven snow, something I had never seen before:

Today, September 24, the adult moth emerged, enabling the identification as Sabulodes aegrotata. After photography, I released it along the Lochside Trail near Blenkinsop Lake.

This was an interesting find, because I had never before seen a moth pupa as white as this one. Also, the caterpillar apparently has the English name Omnivorous Looper, suggesting that it is quite a well-known caterpillar, yet none of the images of the caterpillars of S. aegrotata that I could find on the Internet look at all like this one.
