SCUTELLEROIDEA OF IOWA Or 
Many specimens are at hand from practically every locality 
visited. At some seasons this bug is often abundant and Lugger 
reports it aS injuring raspberry and blackberry plants. Osborn 
(Proc. la. Acad. Sci., I, Pt. II, 121, 1892) records the species for 
Iowa and says, ‘‘Common, sometimes injurious on grape; also 
reported destructive on potato.”’ 
At Lake Okoboji in the summer of 1916 this was one of the 
most abundant species found in the vicinity of the Lakeside 
Laboratory during June and the first part of July. It was found 
commonly in wooded areas and along the edges of woods, espe- 
cially in damp situations. On June 19, this species was swept 
in great numbers from black mustard (Brassica ngra Koch.) 
growing in a small cleared area in the woods south of the Lab- 
oratory. Over one hundred specimens were collected in a few 
strokes of the hand net. On June 22, the species was found in 
some numbers on one of the parsnips (Thaspiwm aureum Nutt.). 
At Iowa City on July 9, I once found great numbers of these 
bugs on the blossoms of wild carrot (Daucus carota Linn.) 
growing in a small uncultivated area near a garden. At this 
time also several pairs were taken in copula. Specimens have 
also been taken upon mullein (Verbascum thapsus Linn.). In 
the hilly region about Decorah on August 10, in the woods and 
along the edges of the woods, we found the species very com- 
mon; most of the specimens were taken from wild raspberry 
(Rubus sp.). By far the largest number of our specimens have 
been taken in July in which month the insect appears to reach 
its maximum of abundance; however, the bugs are often com- 
mon uniil late in August. My latest seasonal record is Novem- 
ber 5 when a single specimen was swept from dead weeds. 
Other food plants recorded for C. bimaculata are figwort 
(Scrophularia nodosa Gray), crowfoot (Ranunculus sp.), cur- 
rant, blackberry, mint and thistle. 
Olsen (Bull. Brooklyn Ent. Soc., VIII, no. 4, 54, 1913) re- 
‘cords the interesting observation that while conducting breed- 
ing experiments of C. bimaculata he found a male in the act of 
sucking dry the eggs deposited on the food plant, ‘‘moth mul- 
lein,’’ by a female only a short time before.
