Habits 
Where found, and methods of concealment 
It is not always easy to find chrysopid larvae. The different species 
oceur in fairly well-defined habitats, and the larvae usually rest 
extended in crevices of bark, on twigs, on flower clusters, or in rolled 
leaves. But the somewhat clear body contents of the young larvae 
blend with the translucent leaves and make the larvae difficult to be seen. 
Very often they rest on a dead patch in a leaf or in curled-up dried 
leaves and their predominating reddish color renders them almost indis- 
tinguishable. 
The most favorable place to search for larvae of Chrysopa oculata 
is on herbage where aphids or young scales are abundant. But even 
here the larvae are rarely found in numbers. Thirty small larvae of 
this species were placed on a large stalk of lamb’s-quarters which was 
heavily infested with the black aphids so frequentiy found on them. 
The next day a search of five minutes was necessary before the first larva 
was found. Only three or four were found on the plant, but as many 
more were found on plants near it. 
The species frequenting herbaceous plants and shrubs are C. oculata 
with all its varieties (including the two nominal species chlorophana 
and albicornis), C. rufilabris, C. plorabunda, C. chi and its variety 
upsilon, and C. interrupta. On trees such as the maples that are com- 
monly planted for shade, the chestnut, and the elm, C. mgricorms, C. 
rufilabris, and C. quadripunctata are most commonly taken. C. har- 
risw was taken on pine and oak, and Allochrysa virginica and C. line- 
aticornis on oak. 
Trash-carrying larvae 
The trash-carrying larvae of Chrysopa lineaticornis have been 
found on linden trees (on both trunk and leaves), on small oak and 
hickory saplings, on honeysuckle, and on underbrush in general. They 
prefer a well-shaded locality. Both C. bimaculata and C. lateralis were 
sent to the writer, by state nursery inspectors, from Florida, where 
they are said to be abundant on citrus trees. C. cockerelli larvae were 
found on the trunks of maple, linden, and apple trees. 
The trash carriers build over the abdomen a hollow hemispherical 
packet. A dorsal view of one of these larvae in most cases reveals no 
larva at all, but merely a little clump of cottony material, for, when the 
larva is quiet, the head, the tail, and the legs are drawn in and thus the 
larva is largely concealed. But when it begins to move, the head and 
2The word packet is used here because, first, there are many kinds of material 
brought together, and secondly, the mass is not on the larva’s back by accident but 
is constructed by the larva. It is literally a little pack of debris.
