Chewing Insect

The problem may be chewing insects such as grasshoppers, beetles, caterpillars, etc.. Have you looked at the undersides of the leaves for a caterpillar? If you don't see an insect, we would normally suggest you cut off all the damaged foliage but since your plant has so many leaves affected, leave them be and check the unaffected leaves several times a day to see if it's on-going. Chewing insects are usually large enough to see with the naked eye, but they can be green, so look closely. If it is a chewing insect, spray with an organic control such as Spinosad - it has a 7-10 day residual - but spray in the early evening after the bees have returned to their hives. Once the spray has dried it is safe for beneficials. There are also synthetic systemics but make sure it is formulated for photinias. Suggest you show a few of these leaf samples to a horticulturist at a garden center for confirmation of the problem and suggested controls.

The problem is likely chewing insects rather than sucking insects. Likely the caterpillar you saw or could also be some type of beetle or grasshopper? But without seeing the actual pest, we can't say for sure. Look to see if you see any sign of insects- top and bottom of leaves, day and at night with a flashlight (although the grasshopper may be long gone). If there are small black dots, these might be excretions for the insects. You can spray with an organic control effective against chewing insects such as Bt (caterpillars). insecticidal soap or Spinosad. Once the leaves and flowers are damaged, they will not recover but try to control future infestation. Bt is a contact insecticide and Spinosad has a 7-10 day residual. Spray Spinosad in the early evening after the bees have returned to their hives. Once the spray has dried on the plant it is safe for beneficials. Suggest you show your photo or perhaps capture a few in a bottle as well as snip off a damaged frond for a local garden center to confirm their identity.

The problem with chewing insects such as grasshoppers, beetles, caterpillars (too numerous to name) etc. is they move about and often are difficult to spot among the green foliage. Chewing insects can be large enough to see with the naked eye, but they can be green, brown, black, etc. so look closely and pluck off any you see on this plant or its neighbors as long as the infestation is not too extensive. If it is extensive, maybe you can spray with an organic control for chewing insects recommended by your local garden center, such as Bt or Spinosad. Bt is a contact only control and Spinosad has a 7-10 day residual but spray Spinosad in the early evening after the bees have returned to their hives. Once dry it is safe for beneficials. However, the most benign control is pick and squish. Also look for slime trails to see if the damage is due to slugs/snails, but we think it is likely a chewing insect.

The problem may be chewing insects. Have you looked at the undersides of the leaves for a caterpillar? If you don't see an insect, we would normally suggest you cut off all the damaged foliage but since your plant is still immature without too many leaves, leave them be and check the unaffected leaves several times a day to see if it's on-going. Chewing insects are usually large enough to see with the naked eye, but they can be green, so look closely. If it is a chewing insect, spray with an organic control such as Spinosad - it has a 7-10 day residual - but spray in the early evening after the bees have returned to their hives. Once the spray has dried it is safe for beneficials. There are also synthetic systemics but make sure it is formulated for edible herbs. Suggest you show a few of these leaf samples to a horticulturist at a garden center for confirmation of the problem and suggested controls.

The problem with chewing insects such as bug larvae or grasshoppers, beetles, caterpillars (too numerous to name) etc. is they move about and often are difficult to spot among the foliage, but if there are black dots on the foliage, it is the excrement of chewing insects. Chewing insects can be large enough to see with the naked eye, but they can be red, orange, green, brown, black, etc. so look closely and pluck off any you see and dispose in a bucket of soapy water as long as the infestation is not too extensive. If it is extensive, you can spray with an organic control for chewing insects recommended by your local garden center such as Bt or Spinosad, but follow application directions. Also show some of these leaves or this photo to a horticulturist at your local garden center for confirmation of the problem as well as recommendations for control but make sure it is formulated for vegetables.

The problem with chewing insects such as bug larvae or earwigs, grasshoppers, beetles, caterpillars (too numerous to name) etc. is they move about and often are difficult to spot among the foliage, but if there are black dots on the foliage, it is the excrement of chewing insects. Chewing insects can be large enough to see with the naked eye, but they can be red, orange, green, brown, black, etc. so look closely and pluck off any you see and dispose in a
bucket of soapy water as long as the infestation is not too extensive. Another chewing insect
is the earwig, but it is nocturnal and seeks refuge in dark, moist areas during the day so
spotting them is difficult. Earwigs favorite food is newly emerging plants with tender foliage as
well as flower buds. A simple method to trap them is to roll up a moistened newspaper in the
late afternoon by your plants (earwigs are attracted to warm, dark, moist areas for cover and
for their habitat) and dispose of the newspaper and earwigs in the trash in the morning or
shake the earwigs out into a pail of soapy water. If it is extensive, you can spray with an
organic control for chewing insects recommended by your local garden center such as Bt (Bt
is a contact spray only) or Spinosad (7-10 day residual), but follow application directions. Also
show some of these leaves or this photo to a horticulturist at your local garden center for
confirmation of the problem as well as recommendations for control but make sure it is
formulated for your specific plant.

The plant resembles a species of Acanthus, common name Bears Breech.
