Explanation of Names
theca=pouch or basket
This perhaps refers to the distinctive way the female carries her egg mass under the upturned rear portion of her abdomen.
Females produce an egg mass that they carry under the rear protion of the abdomen in an orange ball. In the evening they place the mass among vegetation in shallow water, and it expands to strands oup to a meter in length. Another source states that sometimes, several females will oviposit close together, this leading to high densities of young numphs in certain shallow waters.
