At last, the first butterfly of the season here in north Jersey! Cool (temps in the low to mid-50’s), windy and overcast… I guess it got tired of waiting for optimal conditions. The only other Lepidoptera in evidence were a fresh Grote’s Sallow (Copivaleria grotei) and abundant day-flying micro-moths, mostly Bare-pateched Oak Leafrollers (Pseudexentera spoliana).
