have a couple of caterpillars on my dill plant and would like to
know what they will turn into. They are green, the same colour as
the dill. Can you tell me what these will turn into?
caterpillars sound like they are "green looper" caterpillars, Thysanoplusia
orichalcea or Chrysoidiexis eriosoma. They are the most
common green caterpillar in the garden and affect a wide range of
vegetable and ornamental plants.
They will pupate and
turn into a small nocturnal moth with brown and gold wings. They
can be quite damaging, eating large numbers of holes in the leaves.
If you wish to control them you can spray with an appropriate insecticide.
However, since they are on herbs, you may wish to remove them by
