The spermatophore is a package of male sperm that is deposited on the female. The researchers were able to monitor the sizes of the spermatophores and found that its diameter per copulation decreased in males that mated with many partners. The scientists wrongly hypothesized that this decrease in average diameter might result from the males rationing their sperm; it turned out, however, that they were running out of resources to distribute. As a result, the females sought more mates to accumulate enough sperm to fertilize all their eggs.

Scientists have discovered that with fewer males, females get more frisky.  And get your mind out of the gutter, they’re talking about butterflies.
