here's a pic of a very stoned and sticky bumblebee

[Kush Over]

I got a moth stoned once and it died. Altough that was probably due to suffocation as i forgot to lift the glass off it once i'd blown the smoke in.

It'd be rather difficult to get a moth stoned, the same applies to just about any generic insect and some spiders you may find.

Why?

Because moths breath through tiny air holes lining their bodies. These air holes, called spiracles, can close when impurities in the environment [ i.e.: the air ] are detected, sometimes up to hours at a time. They've got rather elaborate respiratory systems; just about every segment of that moth's body was covered in these spiracles; the spiracles then leading to an atrium, a relatively large tracheal tube behind each atrium. They're very selective about what they choose to breath.

Maybe the carbon in the smoke accumulated on it's wings and body, resulting in what you mentioned as suffocation. But it didn't die of being stoned -- it wasn't stoned at all.
