The eggs of some butterfly and moth species vary to give females control over the paternity of their offspring, according to new research. The new study reveals for the first time that the number and location of micropyles (small openings in the outer surface of a female insect's eggs which allow sperm to enter) are driven by a degree of female promiscuity.
