Can anyone point me in the direction of literature and/or research on
levels (lux) of artificial light required by tropical butterflies in order
to fly. I know there different requirements between species, I'm looking
for info. concerning Papilionidae (eg Papilio spp., Graphium spp.);
Nymphalids (eg Hypolimnas spp., Precis spp., Charaxes spp., Hamadryas
spp.); Danaus spp.; Caligo spp.; Heliconidae etc.
I'm also wondering if in addition to intensity, there are wavelength
requirements.
Any help, advice, info. greatfully appreciated.
Thanks
