This post was to the s.b.entomology.lepidoptera so your methods of
communication are going to be a bit simplistic. :-) However, insects
do communicate with each other and with other things in many ways:
Many insects use pheromones to attract the opposite sex - sometimes
other over quite large distances. Many pheromones are available
commercially and could be obtained to see if you could attract things.
You could also include eye-spot and warning colouration, which shows
the insects communicating with their potential predators! :-)
I know you can also lure the large, metallic blue Morpho butterflies
using bits of blue tin-foil - I've done it and it can be quite fun :-)
The males come down for a closer examination - presumably to fight off
an intruder - one chap I know stuck some tin-foil in his hat and the
next thing he was getting beaten about the head by a huge blue
butterfly! That could be quite impressive - if your budget is up to
shipping Charlotte & the crew out to South America :-)
Other insect groups use sound (as in the grasshoppers & crickets) but
I can't think of many examples in the world of lepidoptera though. I
know the Central/South American Hamadryas spp. ('Crackers') make
clicking sounds in flight but I am not sure if this is comminication
between butterflies or to scare off predators.
I know Charlotte PhD'd in Chimp communication but it would be nice to
see a program that featured plenty of non-chimp stuff too :-) I'll
post more examples if I can think of any...
