To answer the query about thermography, I have utilized the technique
on groups and individual (including flying) bees. It is a pretty easy
to use system with a video camera sensitive to infra red radiation. The recorde
images are then processed via desk top computer. This includes color renditon
of temperatures. Agema is a U.S. manufacturer. The units are steep costing
about $90k. Smaller capacity point infra red instruments are available for
under $1000. These are nice for reading single or a few temps on surfaces.
The advantage of the AGgema type is that one can obtain hundreds of temps
on the surface of even a single bee. I can provide more information if
anyone is interested.
