butterfly species


Silver-spotted Skipper (Hesperia comma)

… is a butterfly of the ‘skipper’ family  Hesperiidae, found through out northern North America and Eurasia. It is known as the Common Branded Skipper in North America, where the butterfly Epargyreus clarus, a spread-winged skipper, also has the common name of “Silver-spotted Skipper".
Females lay single eggs during August and September on the leaf blades ofSheep’s Fescue, Festuca ovina, the only foodplant, and occasionally on nearby plants. Like other skippers the larvae construct small tent-like structures from leaf blades and silk from which to feed. They enter the pupal stage after 14 to 15 weeks at the base of the foodplant. Pupation takes 10 to 14 days, and as with most butterflies the males emerge first…

Florida declares two butterfly species extinct as pollinator crisis worsens
by Alexander Holmgren
Conservationist’s faced a crushing blow last month as two butterfly species native to Florida were declared extinct. 

“Occasionally, these types of butterflies disappear for long periods of time but are rediscovered in another location," said Larry Williams, U.S. Fish and Wildlife state supervisor for ecological services. We think it’s apparent now these two species are extinct." 

Neither species has been seen in any environment for at least nine years, the latter of the two not being seen since 2000. This calamity is only made worse by the fact that so much could have been done in order to save these creatures. The first species, the Zestos skipper butterfly (Epargyreus zestos oberon), had strong bodies with large black eyes and large wings that were adorned with spots that looked like eyes. While the Zestos skipper was visibly declining in its environment, the subspecies was denied access to the U.S.’s Endangered Species Act (ESA) because of the confusion between it and other skipper species in the Bahamas. In the end, what was thought to be a bountiful reserve in the Bahamas proved to be a completely different species. By the time the mistake was realized it proved too late. 

The Rockland grass skipper butterfly (Hesperia meskei pinocayo), an amber golden insect with club like antenna and black eyes, was similarly thought to be making a comeback as the species that had not been seen since the 80’s was spotted back in 2000. But is now believed extinct…
