The Neotropical apple snails that lay subaquatic, gelatinousegg masses (species of Asolene, Felipponea and Marisa) havereceived less scientific interest than those apple snails that lay masses of calcareous shelled eggs above the waterline (genus Pomacea). Basic and applied research has concentrated so faron two species of Pomacea that have become important pestsof aquatic crops (mainly rice) as well as drivers ofecosystemic changes in invaded wetlands. Up to now, conservation orientedresearch and conservation efforts have been aimed only at theFlorida apple snail, Pomacea paludosa, which is the staplefood of an endangered raptor, the snail kite. As part of a broader research program that commenced five years ago on the natural history, invasion and conservation biology of Argentinean apple snails (Martín et al., 2013), weundertook a study of the life cycle and the reproductive andthermal biology of Asolene platae.
