The Butterflies of Massachusetts by Sharon Stichter

This wonderful resource presents new information on the abundance and distribution of Massachusetts butterflies based directly on Massachusetts Butterfly Club sighting data.

The Caterpillars of Massachusetts 2009 by Sam Jaffe

After a fantastic 2009 season spent seeking out and photographing many of our more spectacular caterpillars, Sam has combined his notes on Massachusetts' caterpillar life histories into a single document. Now, with the help of the Massachusetts Butterfly Club, these notes are available online, as a pdf, with accompanying thumbnail links to Sam's relevant photographs.

These notes should not be mistaken for an exhaustive resource, but the information provided regarding caterpillar location, hostplant, season, and behavior might be especially relevant to all Massachusetts butterfly and moth enthusiasts.
