There are thus two female openings, one for copulation, the other for oviposition, as well as a male opening.
The first act of the female after oviposition is to wrap her eggs in a casing of silk commonly called the cocoon.
So far as is known at present, all sticklebacks construct a nest for the reception or the spawn, which is jealously guarded by the male until the young are hatched, which event takes place in from ten to eighteen days after oviposition.
Their formation from buds which normally would have yielded leaves and shoots is explained by Parfitt as the outcome of an effort at fructification induced by oviposition, such as has been found to result in several plants from injury by insect-agency or otherwise.
Temporary oviducts are formed between the "spermduct" and the germinal epithelium at each oviposition.
Pairing and oviposition take place on land; the male seizes the female round the waist.
After oviposition, which may extend over several weeks, the female dies.
Under favourable conditions, when food is obtainable, growth is rapid, the time from the hatching of the young until it reaches maturity and dies after oviposition being, for example, about eleven weeks in R.

Thus the characteristics of the currant-gall of Spathegaster baccarum, L., which occurs alike on the leaves and on the flower-stalks of the oak, are obviously due to the act of oviposition, and not to the functions of the parts producing it; the bright red galls of the saw-fly Nematus gallicola are found on four different species of willow, Salix fragilis, S.
