Before silverfish reproduce they carry out a ritual involving three phases, which may last over half an hour. In the first phase, the male and female stand face to face, their quivering antennae touching, then repeatedly back off and return to this position. In the second phase the male runs away and the female chases him. In the third phase the male and female stand side by side and head-to-tail, with the male vibrating his tail against the female.[11] Finally the male lays a spermatophore, a sperm capsule covered in gossamer, which the female takes into her body via her ovipositor to fertilize her eggs.
Stings spider to paralyze it, lays it eggs in the spider, they feed on it, apparently leaving the vital organs to last to keep it alive as long as possible. BOKE.
remember once when I was a kid some ladybirds had laid eggs or something in the taps of the bath so for ages sometimes when I would run a bath bits of dead ladybird would come out of the tap and float in the water.
