We are nearing the end of summer – but there are still a few nice moths around. Jeremy Tatum writes: I have been asked more than once how to tell whether a moth is a geometrid or a noctuid. One possible answer, which works most (not all!) of the time, is that geometrids are landscape, while noctuids are portrait. This is illustrated by these two moths that I photographed today. The first was at my Saanich apartment. The second was from a caterpillar found on Gumweed at Island View Beach.

Also seen (but not photographed) yesterday, at Swan Lake Nature House, was a Common Emerald Moth.
Val George photographed the moth shown below at his Oak Bay house today. This is a puzzler. It is obviously one of the difficult pair Triphosa haesitata / Coryphista meadii – but which one?!!! Libby Avis and Jeremy Tatum – after careful examination – agree that it is Coryphista meadii: 1. Conspicuous dark discal spot. 2. Fourth tooth on outer margin of hind wing short. 3. Slightly falcate wingtips.
Libby tells me of another complication: Coryphista meadii has had a name change – it is now Rheumaptera meadii. For consistency with earlier photographs of the species within this site, I label it here with its old name.

Jeremy Tatum writes: I have seen several Banded Woolly Bears recently. October is their peak month. They are often abundant at Panama Flats.
