The body surface of aquatic invertebrates is generally thought to be hydrophilic to prevent the attachment of air bubbles. In contrast, some interstitial invertebrates, such as kinorhynchs and some crustaceans, have a hydrophobic body surface: they are often trapped at the water surface when the sediment in which they reside is mixed with air and by: 4.

Some soli- tary bees lay their eggs soon after mating, so sperm are stored for only a short period. In contrast, all social and almost. ently based on adult morphology. Inattention to larval morphology is responsible for the many unnatural groups of species now known to exist within the tribe, especially for groups defined by Lane and Cerqueira () and Lane () for New World taxa and Mat- tingly (, 1) and other authors for Old World taxa.
