THE GOOSEBERRY FRUIT-WORM, Pempelia grossularue, Pack- 

 ard.— PI. 2, Fig. 17. 



(Lepidoptera, Phycida?). 



On June 8th, I received from Mr. Geo. II. Cherry of Hematite, a 



number of diseased gooseberries, with an account of their prema- 



[Fig. 79.] turely turning red and rotting. The cause was a 



§-^^d^« smooth thick glass-green worm which is more 

 "-'-'- *■■'■* -.-'-y fully described below. Subsequently on the 12th 

 . '-^ of the same month, I received the same species 

 a b of worm with a similar account of its work, from 



Mr. Stephen Blanchard, of Oregon; on the 16th from Jos. F. Bryant, 

 of Bethany, with the statement that it was " feeding on and hollowing 

 out" his currants, and on the 17th from Dr. W. A. Monroe of Bloom- 

 ington with the statement that it was destroying his native gooseber- 

 ries and Green gage plums. Mr. A. Fendler and F. R. Allen, both of 

 Allenton, likewise informed me that it entirely ruined their currant 

 crop, and I afterwards found the same insect on the currants and 

 gooseberries wherever I went, and it doubtless occurs over the whole 

 country, for as we shall presently see, it attacks the gooseberry both 

 in the State of New York, Massachusetts, and in Canada. 



Dr. Fitch, in his 3d Report, §149, makes brief mention of it though 

 he was not acquainted with the parent moth. He concludes his ac- 

 count in the following words : " I have sometimes seen bushes of the 

 wild gooseberry with every berry withered and reduced to a mere 

 dry hollow shell, with a cob- web like tube protuding from the orifice 

 in one side. And the present summer a letter to the County <•■ ntle- 

 man, from E. Graves Jr. of Ashfield, Mass., states that for three years 

 past, his k Houghton's seedling' gooseberries have been a total fail- 

 ure from this same worm, as I am assured by the account which he 

 gives of it and- the specimens accompanying his letter." 



As soon as gooseberries and currants are well formed, this worm 

 begins to make its presence known by causing the berries which it 

 infests to prematurely turn red or dull whitish. After eating the in- 

 side of one berry, leaving a hole for the passage of the excrement, it 

 enters another berry, making a passage way of silk, until it draws to- 

 gether a hunch of currants, or two or three gooseberries as the case 

 may ba. The berries thus attacked sometimes drop, but more gener-
