moths sense heat?

[John.Snyder at furman.edu]

Someone asked me the following question, and I pass it on to the group.  Do
moths specifically sense heat, and respond behaviorally to its presence?
The question was asked in context of moths circling around artificial light
sources, which of course can also be heat sources.  I suppose the question
could be enlarged to include all lepidoptera.
