It's my understanding the the venom of different insects utilizes different alkeloids and so that would incite reactions to stings of one type of insect and not another. By the way, was stung by a scopion several years ago and had a little soreness and numbness in the area of the sting. Otherwise, not very affected. Was the mildness of the reaction due to tollerance built up doue to bee stings? Would like to think so. MIKE Sugar Land, TEXAS [log in to unmask]
