the caterpillars of some Tortrix moths, can cause a great deal of damage to small Passiflora.

is easy to spot as the leaves are rolled up into a tube, or if too stiff
flattened as in the P. actinia leaf above. The
caterpillar will turn into a small brown pupa hidden in the leaf which will
then emerge as a small brown moth. Best policy is to tear off the rolled up
leaves if the plant is small and suffering badly from the damage. You have to
be quick though as otherwise the leaf rollers will bale out and absail down
their silk threads to vanish into another part of the plant. Larger plants with
just a few rolled leaves need no treatment at all.
accidentally found one effective treatment when I gave quite a strong foliar
feed to a young Passiflora and the next day found a dozen leaf
rollers in the surrounding saucer-they clearly did not like the taste!
