Since most of us recognize the potential of these insects, such trapping is usually accidental. As a child, it took me several painful summers before I consistently associated the clover blooming on my grandfather's lawn with active honey bees. Normally stinging is used only as a last resort because the insect is temporarily defenseless when the venom is used up. In the case of the honey bee, the bee dies. A number of insects, including the harlequin bugs and the so-called stink beetles, will spray.
Sprays vary in toxicity.
If you are not sure about an insect you might do well to keep your eyes away from insect behinds. If you must handle these creatures, keep them on the tougher skin like the palms of your hands. It is possible to violate an insect's space and like us this varies from individual to individual and situation to situation. Under these circumstances, some aggravated insects will fly right at your face whether or not they can sting. On the other hand, some insects, even excellent flyers such as dragonflies, have been known to fly into people, apparently accidentally.
