I have some experience and information on lepidopteran (butterflies and
moths) pests of Arabidopsis thaliana in wild or semi-wild conditions.
In Japan, a noctuid pest species, Agrotis segetum (English name: turnip
moth) attacks Arabidopsis.
This species has a very broad host range, mainly in Brassicaceae.
In the eastern U.S., a pierid species, Anthocharis midea (falcate
orange-tip butterfly) was reported to feed on Arabidopsis (See J. A. Scott,
The Butterflies of North America, Stanford Univ. Press, 1986, p.213).
The latter species,whica has narrower host range, might be of interest to
study host plant-phytophagous insect interactions.
It might be possible to isolate Arabidopsis mutants which induce
oviposition behavior of adult insects but does not induce eating behavior
of larvae, or which induce eating reaction but is indigestible or toxic to
"Sometimes solitary eggs positioned at the end of ca. 1-cm long stalks" in
Colin Purrington's reply are likely to be those of racewing, larvae of
which feed on aphids.
