Identification
The ocherous to yellow-orange patch on the hindwing is the primary field mark distinguishing Lerema ochrius from the similar Lerema laccus (Laccus Skipper), which lacks this coloration and shows more uniform brownish ventral surfaces. Lerema ochrius also tends to have slightly more contrasting wing patterns. Genitalia examination or may be required for definitive identification in some cases, particularly for worn specimens.
