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.
The researchers behind the study, based
at the University of Lincoln, UK, suggest that an increased number of
micropyles enables the female butterfly or moth greater control over
fertilisation.
The study is published in the Royal
Society's scientific journal,Biology Letters.
