Because physical speed alone is often insufficient to evade sharp-eyed predators, insects have evolved the most dazzling, deceptive, and devastating defensive repertoires in the animal kingdom. From … Read more

Through the synthesis and detection of semiochemicals—volatile organic molecules secreted into air currents or deposited onto substrates—insects coordinate monumental colonial tasks, attract mates across miles … Read more
