77-17) in triangular resting posture. 3. Same individual in wing-spread resting 
posture. 4. Same individual as final instar larva shortening for pupation. Scales

Foodplants 
Foodplant records for Dysodia are few (Table 1), and involve 
several unrelated plant families. 
Dysodia sica on BCI was found on two species of the Piperaceae: 
Piper marginatum (Figure 5) and Pothomorphe peltata (Figure 6). 
Both species are abundant weeds in the Laboratory Clearing, and 
have similar leaf texture, odor, and growth form. 
Immature Stages 
Egg 
Eggs (Figure 10) are deposited upon the upper surface, near the 
center of larval host plant leaves. Normally only one egg is laid per 
leaf. However, several leaves on a plant may receive them. 
Eggs are yellow-orange, cylindrical, 1.5 mm tall and 0.9 mm in 
diameter. They have a circle of 16-20 papillae around the periphery 
of the top. Except for a smooth area in the center of the top,
