Lepidopterists' Society Season Summary

Important resource for rare Lep. records...

"The Lepidopterists' Society Season Summary [sometimes: LepSoc-SS] is an annual compilation of Lepidoptera records from Canada, Mexico, and the United States. Each year our members submit information regarding range extensions, host plant associations, population dynamics, etc. Automated in 1995, the database contains all records since that time plus Saturniidae and Sphingidae records since 1971."
