Food-Plants of the Clover-Stem Borer.'— Until very re- 
cently the accepted life-history of the clover-stem borer (Zanguria 
mozardit) rested upon the observations recorded by Professor J. H. 
Comstock in the Report of the U. S. Department of Agriculture for 
1879. Briefly stated, these observations showed that the eggs of the 
insect are deposited during June in the stems of red clover; that the 
larvee hatching shortly after feed upon the pith of the stalk, pupate 
within the burrow the same.season, and emerge as beetles during 
August, September, and October, hibernating as adults. As to reme- 
dies, Professor Comstock says: 
** It seems probable that where clover is regularly cut in early sum- 
mer, and again in fall, this insect will not increase to any alarming 
extent ; but where this is neglected, or where there is much waste 
clover, it may do considerable damage. 
Essentially these facts and recommendations have been rehearsed 
by a number of writers during the last decade; but in a recent article 
in /nsect Life (Vol. IL, pp. 346-7), Mr. F. H. Chittenden has shown 
that this species develops in horse-weed (Ambrosia trifida), and prob- 
ably also in nettle (Urtica dioica), daisy fleabane (Erigeron » amosus), 
and ox-eye daisy (Chrysanthemum leucanthemum). Mr. F.M. Websur 
has also found a larva indistinguishable from that of the present sp. cies 
in stems of timothy (PAeum pratense). 
My observations upon this species began the present summer, and 
show that the insect has even a greater range of food-plants than these 
facts would indicate. Between July 12 and August 12, larve, pupe, 
or adults of Z. mozardii were found in the stems of the following 
plants: Yarrow (Achillea millefolium), sweet clover (Melilotus alba), 
wild lettuce (Zucfuca canadense and L. floridanum), bellflower ( Campa- 
nula americana), thistle (Cnicus altissimus), fleabane (Zrigeron phila- 
delphicus), and nettle ( Urtica gracilis). 
A large number of stems of red clover were examined for the insect, 
but none were found. Hence it seems probable that the species pre- 
fers uncultivated plants, especially the composite, for breeding pur- 
ses. —CLARENCE M. WEED.
