Could you explain how does a Malaise trap work? What I want to know is whether the ten gets set during the whole biodiversity peak, or for less time. Another thing rattling my mind is what to do with the enormous ammount of insects one in theory catches is this kind of trap. I'll be choosing some groups for study, but what should I do with the other insects? To those of you who have already used this method, what do you do with insects that are not of interest?
