Did You Know…
The common name of the ‘skippers’ group probably refers to the bounding or skipping and erratic flight style often close to the ground. Skippers are most likely more closely related to moths than true butterflies as the pupal stages are protected within silken cocoons rather than the exposed and unprotected chrysalis of most butterflies.
