When to look: Late April to summer
What to look for: "Skeletonized" leaves. Feeding is almost exclusively in the areas between the leaves' veins.
Where to look: Leaves, particularly those near egg-laying sites. Often difficult to spot early in the season as the leaves are emerging and the larvae are small.

Larvae can cause heavy damage to young leaves before they even fully expand.

Typical "skeletonized" pattern of damage caused by larvae feeding. Note how the damage is almost exclusively between the veins. Compare with adult feeding damage.

Larvae and larvae feeding damage is difficult to spot when the larvae are still small.
