This skipper is apparently single-brooded; the Sep- 
nber record from Jersey County is unusual. We have 
t seen the specimen on which it was based, and the 
ord may be erroneous. It appears from the available 
ta that hianna is widely distributed but rare and er- 
ic in Illinois.

This insect is apparently restricted to northeastern

It appears that this distinctive skipper is established 
outhern Illinois. The record from Pulaski County 
the first following its original description (Irwin 
E. dukesi was once believed to be restricted to swamps 
their immediate vicinity, but it has recently been 
nd, in the southern portions of its range, in drier 
ations as well. Two sedges, Carex lacustris and C. 
linole pis, are the probable hosts of dukesi. Both sedges 
rin Illinois, the former being more confined to true 
mp environments than is the latter. In the southern 
tion of the range of dukesi, C. lacustris does not occur 
the insect utilizes C. hyalinolepis (Irwin 1972). Be- 
¢ of the rather wide occurrence of both sedges in the 
Hi 
state and the presence of dukesi as far north as Michi- 
gan, it seems possible that the skipper may occur else- 
where than in the extreme southern counties.

This is another species that is found mainly in marsh- 
es and boggy meadows. It is local but may be common 
where found. It is apparently limited to northern TIli- 
nois. There is one brood, June 20 through August 9.

E. bimacula (Fig. 1) is sporadic but locally common. 
Like other members of the genus, it occurs in bogs and 
wet meadows, and it appears to be limited to the north- 
ern portion of the state. See discussion of Oarisma 
powesheik (Parker), below. The species is single-brood- 
ed, June 19 through July 20.

Illinois records.—Map 5. 
The dun skipper is common and generally distributed 
throughout Illinois. Although Klots (1951) suggested 
that there is but one brood and gave dates of flight from 
June through August, we have records of the species 
from April 28 through September 16. This extended 
flight period strongly suggests that the species is at least 
double-brooded in Illinois.
