(Table of Species)

The Skippers (290 NA spp) are diurnal, frenetic fliers with spindle-shaped antennae.  Two subfamilies including 22 species   have been collected at Cedar Creek. The Hesperiinae are grass feeders, while the Pyrginae favor legumes.

HESPERIINAE
The Dusted Skipper (Atrytonopsis hianna) is a common early summer inhabitant of old fields. The Arctic Skipper (Carterocephalus palaemon) is an early summer species generally found in open woods but occasionally in fields. The Least Skipper (Ancyloxypha numitor) is common at lake/pond edges. The Hobomok Skipper (Poanes hobomok) is common in open woods in early summer. The Tawny edged Skipper (Polites themistocles), Peck's Skipper (Polites peckius) and the Dun Skipper (Euphyes vestris) are fairly common in old fields in mid-summer. The Delaware Skipper (Atrytone delaware) and the Broken Dash (Wallengrenia egeremet) are less frequently encountered. The Long Dash (Polites mystic) is common in marshy areas. Leonardus Skipper (Hesperia leonardus) is a fall species occuring in a few of the better prairie and savanna regions of Cedar Creek. The Mulberry Wing (Poanes massasoit) and the Broad Winged Skipper (Poanes viator) are two uncommon sedge marsh species. Rare species confined to sedge marshes include the Dion Skipper (Euphyes dion), the Black Dash (Euphyes conspicua), and the Two-spotted Skipper (Euphyes bimacula). Amblyscirtes vialis? has been seen, but unfortunately not collected.
**Pompeius verna has been collected near here.

Juvenal's Dusky Wing, Erynnis juvenalis (Quercus,Corylus) is commonly seen at Puccoons (Lithospermum) in savanna regions in early summer. The Dreamy Dusky Wing, Erynnis icelus (Populus) and the Sleepy Dusky Wing, Erynnis brizo (Quercus) are infrequently encountered. The Silver-spotted Skipper, Epargyreus clarus(Amorpha, Lespedeza) is fairly common. The Northern Cloudy wing, Thorybes pylades (Trifolium, Lespedeza) and the Common Sooty Wing, Pholisora catullus (Amaranthus, Chenopodium) are infrequently encountered.
