Species Hesperia dacotae - Dakota Skipper

Overviews of each region of the state, more detailed sections on habitats such as mountain ranges, deserts, and canyons, and very specific information on individual locations - you'll find out which side of a gulch gets the morning sunlight and how far down a creek the swallowtails puddle.

Other chapters discuss where to go and what to look for in each month of the year (in February, willow ragwort flowers near Sonoita Creek attract Arizona Dusky-Wings), provide brief descriptions of many species of butterflies and skippers, and review the state's butterfly gardens.

I serendipitously discovered this little gem while checking out the online Field Guide to the Syrphidae of Ontario. Always looking for more caterpillar references, I went looking for a copy and found it for sale at Kettle Creek Conservation Authority. I paid US$12 with a credit card over the phone and it arrived today.

It's a small book but packed with lots of information. It aims to cover the easily identified caterpillars of Southern Ontario. With that in mind, you won't find any range information and the seasons are surely specific to that region. Nonetheless, I recognize most of the species from my own area here in Georgia, so it certainly has value as an identification aid.

Just saw this mentioned on a listserve--I don't have a copy. It looks like it could be very useful. Despite the 2005 publication date, it is apparently already available.
