352 INSECTS INJURIOUS TO THE RED CURRANT. 



ATTACKING THE FEUIT. 



No. 214. — The Currant Fruit-worm. 



Eupithecia interruptofasciata Packard. 



This insect is readily distinguished from the gooseberry 

 fruit- worm by the number of its legs, which are only ten, 

 while the gooseberry fruit-worm has sixteen. The currant 

 fruit-worm is a span-worm ; that is, it arches its body, when 

 in motion, with every step. When full grown, it is about 

 five-eighths of an inch long, and varies in its color and mark- 

 ings. Its body is pale greenish-ash, or yellowish green, with 

 a dark -colored line down the back, and another on each side, 

 but occasionally this latter is wanting. Sometimes there is 

 a row of dark-colored, lozenge-shaped spots along the dorsal 

 line, and in some instances there is a second lateral line lower 

 down the side. On the hinder part of the terminal segment 

 there are two short greenish spines. The head varies in color 

 from yellowish or greenish to light brown ; the under side of 

 the body is white or pale greenish, with a yellow line in the 



middle. 



When full grown, it draws several leaves or other suitable 

 protecting material together, fastens them with silken threads, 

 and within the enclosure changes to a chrysalis, from which 

 eventually the moth escapes. 



The fore wrings of the moth are of a bluish-gray color, 

 Avith a bluish dot near the centre of each, and a dark line 

 crossing them immediately beyond the dot. 



No. 215.— The Currant Fly. 



Epochra Canadensis (Loew). 



This insect is occasionally found attacking the fruit of 

 both the red and the white currant. In its perfect state it is 

 a small two-winged fly, which lays its eggs on the currants 

 while they are small; the larva enters them while still green, 

 and feeds on their contents, leaving a round, black scar at
