Flattened scoli have a plumose or leaf-like appearance (e.g., A. 
celerio, serpa, paraena ) which is due not only to the arrangement of 
spines in two opposite rows along the scolus, but also to the 
flattening and widening of those spines which may take on 
spatulate, elliptical, or lanceolate forms, and may be so crowded 
that they overlap one another. In the case of extremely condensed 
scoli, the spines appear to fuse with one another (see A. serpa in 
Muller, 1886). 
Larval Behavior 
Upon hatching, a larva eats some or all of its egg shell and then 
feeds on the leaf tip leaving the midrib intact. Larvae rest out on the 
midribs which they have exposed, and eventually extend them by 
addition of fecal pellets held in place with silk. Most larvae fashion 
several such supports during each instar, often using lateral veins 
instead of the midrib. When not feeding, Adelpha larvae rest out on 
their supports, facing away from the leaf; molting takes place on the 
support as well. After they molt to the final instar, larvae abandon 
their supports and thereafter rest on the upper surface of a leaf.
