CBIF (Canadian Biosytematics Information Facility) seems to be up and working again (for moths). It’s a difficult system to use for identification, but it’s great when you want to show different species side by side. For those who like this feature (like me!), this is good news. It’s been down over a year, and I’m glad to see it up and running again.
I like the way they display front/back of butterfly wings in one photo.
