Illinois records.—Map 29. 
Records of the hoary edge are widely scattered 
throughout Illinois, indicating statewide distribution. 
A. lyciades is single-brooded and comparatively scarce 
in the northern portion of the state, double-brooded 
and more common southward. The earliest and latest 
dates are May 11 and September 1. At Elsah, Jersey 
County, the first brood flies from mid-May to mid-June 
and the second, fewer in numbers, in late August 
(CLR). The second brood is absent in the north. The 
skipper may be overlooked because of its resemblance 
on the wing to the more common Epargyreus clarus.

The establishment of this scarce butterfly at the 
locality cited is indicated by the fact that Downey en- 
countered it there three times in one season. It may 
occur elsewhere in southern Illinois.

This large, strong-flying and robust skipper is com- 
mon throughout Illinois. Records are from April 6 
through September 28. It is at least double-brooded 
in most of the state.

Illinois records.—Map 31. 
The pipe vine swallowtail is found throughout the 
state and is locally common. There are two broods. A 
spring generation flies from April 24 (Union County) 
through May 31. The summer brood, consisting of 
individuals that are larger than those in the spring 
ie has been recorded from July 2 through Septem- 
ele 20:

The black swallowtail is the most common membe: 
of its. family in Illinois, and it is generally distributed 
Like other swallowtails, its spring brood consists o 
smaller, brighter individuals than the later generations 
The earliest date is April 3 and the latest October 14 
There is a record from Evanston, Cook County, Febru 
ary 18, 1896, Snyder (FMNH) but this is probably th 
result of premature emergence, perhaps from a pup 
protected by a heated structure or influenced by ak 
normal weather.

Illinois records.—Map 33. 
The largest of our butterflies, P. cresphontes h 
been recorded from localities in all parts of Illino 
but it is sporadic in occurrence and never common. I 
broods conform to those of other swallowtails in Il 
nois, the first brood being smaller than the secot 
both in size and number of individuals. The -spri 
generation flies from May 14 (earliest date on recor¢ 
through June and the summer brood appears near t! 
end of July. The latest date of capture of this spec! 
is August 24, but the butterfly is probably on the wi 
into September in the southern counties. The gia 
swallowtail is often seen but less frequently captur 
because of its high, powerful flight. It tends to follc 
flight paths, but seldom rests except to feed upon flowe
