Just saw our first of the year Mourning Cloak in the DeKorte's Lyndhurst Nature Reserve. This cloak looks like something out of the Salvation Army store, but still nice to see.
By the way, according to the North American Butterfly Association Checklist for DeKorte, this butterfly is due to appear around... mid-April.
Checklist is here.

By the way, have you heard that a new free Butterflies of DeKorte Park pamphlet is in the works? We hope to have it ready later this spring.
