Red-footed flea beetle 



Crepidocicra rujipcs Linn. 



A red-headed, blue flea beetle about }i inch long, is sometimes very abundant on 

 locust and apple foliage. 



Specimens of this little flea beetle were taken from badly damaged 

 honey locust foliage at Poughkeepsie, May 21, 1903. 



Description. y% inch long, with head, antennae, legs and prothorax a 

 brick-red color, while the wing covers are bluish and plainly marked with 

 rows of punctures. The ventral surface of the meta- and mesothorax and 

 abdomen black. 



Life history and habits. This little insect is liable to appear in large 

 numbers in early spring, at which time its depredations on locust, apple 

 and other fruit trees may be somewhat serious. Dr Smith states that in 

 New Jersey it also attacks grape. 



Distribution. This is an European form, according to Dr Horn, now 

 widely scattered over the Atlantic region and as far west as Iowa. It is 

 probably generally distributed over this area, since it has been recorded 

 in a number of local lists. 



Locust leaf folder 



Epargyrcus tityrus Fabr. 



Large, pale green caterpillars about 2 inches long, with a red neck and large red head 

 and a yellow spot on each side above the mouth, draw the leaves of locust together and 

 feed by night. 



The caterpillar of this rather handsome butterfly is a somewhat gen- 

 eral feeder, eating freely the leaves of many of the Leguminosae and 

 occasionally being so abundant in New England as to strip the foliage from 

 the common locust and specially the viscid locust, Robin i a e viscosa,
