What's eating my passiflora incarnata?

Fritillary caterpillars

Signs: Larvae (orange with black spines) rapidly strip leaves down to bare stems; whole plant may be defoliated

Control: Hand-pick caterpillars if infestation is severe; tolerate when possible as they are native butterfly larvae; apply Bt (Bacillus thuringiensis) only if defoliation threatens plant survival

Japanese Beetles

Signs: Skeletonised leaves with only veins remaining; damage occurs in midsummer

Control: Hand-pick beetles into soapy water in the morning; do not use pheromone traps near the plant

Aphids

Signs: Dense colonies on new shoot tips; honeydew, sooty mold, and curled leaves

Control: Spray with insecticidal soap or neem oil; attract lacewings and ladybugs as natural predators

Passiflora incarnata pests — FAQ

What is eating my passiflora incarnata?

Passiflora incarnata (Maypop) is the larval host plant for Gulf fritillary, zebra longwing, and variegated fritillary butterflies — caterpillars can completely defoliate plants quickly. Japanese beetles skeletonise foliage in summer. Aphids cluster on new growth. Because it regrows vigorously from the roots, most pest damage, including caterpillar feeding, is tolerated.
