Sometimes the oöthecae are deposited but not concealed. Hafez and Afifi (1956) reported that in Egypt _Supella supellectilium_ attaches its oötheca to a suitable substrate with a gummy oral secretion but leaves the egg capsule otherwise exposed. We (1954) have noticed similar behavior in laboratory colonies of this species and of _Blatta orientalis_, as have Gould and Deay (1940). Cornelius (1853) stated that the female of _B. orientalis_ takes care of the safety of her offspring to the extent of usually dropping her oöthecae in places which are dry and raised above the ground, although rarely one also may find some oöthecae scattered on the ground. For lack of suitable material females of _Periplaneta americana_ sometimes did not conceal their oöthecae (Nigam, 1933). Frequently in laboratory colonies _P. americana_ merely drops the oöthecae loosely in sand or food "in contrast to _P. australasiae_, which almost always went to considerable trouble to fasten their eggs securely and to conceal them with debris" (Pope, 1953). If conditions under which _Nauclidas nigra_ is kept are not suitable, the female will drop her oötheca anywhere (Bunting, 1956). Rau (1940) stated that the female of _Parcoblatta pensylvanica_ does not conceal her oötheca. However, Gould and Deay (1940) stated that this species deposits its oöthecae loosely behind bark. _Ellipsidion affine_ and _Ellipsidion australe_ attach their oöthecae to bark or the underside of leaves but apparently make no attempt to conceal them (Pope, 1953a). The females of most of the above species have no further familial association with their offspring. The eggs hatch with no attention from the mother who is probably not even in the vicinity at that time. The young apparently do not react to the presence of the parent, as such, after hatching. This is not unexpected, as several additional oöthecae may have been deposited by these oviparous females before the eggs of the first oöthecae hatch. However, a different behavior is encountered among species that do not form a second oötheca until after the eggs of the first have hatched (see below) and in the so-called colonial species.
