Development

Development.—In some cases the males are said to deposit their reproductive elements in packets (spermatophores) fixed by a web to the ground. In most cases copulation probably occurs. Scolopendra is viviparous, the others lay eggs. The eggs develop into larvæ, which are either miniature adults (Scolopendridæ and Geophilidæ), or differ from the full-grown forms in having only seven pairs of legs (Scutigeridæ and Lithobiidæ).
