DOLICHOS 



DI'TULAANGUSTIORA'NA. Apricot Moth. As soon 

 in May as one of the leaves of a Peach, Nectarine, or 

 Apricot is seen rolled up, destroy the little caterpillar 

 within the roll, and watch for others, because the eggs 

 of the moth from which that caterpillar came continue 

 to hatch for several weeks. The moth is the Narrow- 

 winged Red Bar, Di'tula angustiora'na. The caterpillars 

 appear during May and J une : they are about half an 

 inch long, are pale yellowish-green, and with the head 

 brownish-yellow. A few bristles are scattered over the 

 body. It is a very active caterpillar, wriggling about in 

 most varied contortions when disturbed, crawling with 

 equal facility backwards and forwards, and letting itself 

 down by a single thread from its mouth. It passes into 

 the state of a brown, shining chrysalis, rolled up in the 

 same leaves, and from this the moth comes forth in July. 

 The moth is very small, not longer than a fourth of an 

 inch. The fore-wings are reddish-brown, in bands of 

 various degrees of darkness. The hind-wings are dusky. 

 It deposits its eggs, probably, upon the branches, where 

 they remain all the winter, and the caterpillars are most 

 frequently found upon the Apricot, but attack most 

 trees, and sometimes damage grapes in vineries.
