Biologists expand on more than 150 years of textbook wisdom with a new explanation for wasp mimicry
The masquerade is almost perfect. Certain moths of the subfamily Arctiinae are marked with a yellow and black pattern. But these day-active insects have wasp waists and their antennae resemble those of wasps. Their transparent wings are folded in a wasp-like way. For more than 150 years there has been a plausible explanation for this type of imitation, which is commonly known as mimicry. It says t
