CLOVER HAY-WORM. 8»» 



Chrysalis liglit brown; 5mm long. The anal segment bears 

 Bix hooks, two dorsal, four lateral. The moths are small, brown^ 

 often nearly black, with white lines and dots marking the wings. 

 They expand 10 m m. 



There are three broods of the moth appearing respectively irt 

 early June, Augnst and September; the larv£e appear soon 

 after. 



The same remedies which are snccessfnl against the clover- 

 seed midge are eflfectual in checking the work of this moth. 

 An Ichneumon parasite was found preying on these by Prof. 

 Comstock. It is Phanerotoma tibialis. It is light brown, with 

 a large dorsal yellow spot, and is 3.5 m m long.

This insect works on dried clover or clover hay while in the mow 

 or stack. It is generally distributed, and scarcely a season goes 

 by that I do not receive specimens, with request for information 

 regarding the natural history and habits of the insect. This be- 

 longs to the same family as the bee moth and the meal moth, 

 Pyralis farinalis, Harr., which is often very common about barns 

 where meal is stored, and which sometimes also feeds on clover 

 hay. 



The color of the larva, Pig. 146, is dark brown, lighter beneath. 

 The intersegmental spaces are darker than the segments, which 

 makes the larvas appear to be ringed. It is 18 m m (f of an 

 inch) long. The cocoon is white, and 13 m m long. The chrys- 

 alis is yellow in colorj length ^ of an inch. The imago, or moth^
