Damsel bugs, Nabidae, are valued predators in agricultural and urban systems. Worldwide, there are considered to be 31 genera and 386 species known, with 11 genera and 83 species from the Neotropical region. While little bionomic information is available for Neotropical nabid species, highlighting the need for future research, the biology of Nabis (Tropiconabis) capsiformis Germar, is representative of the family. N. (T.) capsiformis demonstrated a type I functional response when feeding on bollworm eggs. Under laboratory conditions, total generation time was 51.6 days. Nabids insert their eggs into plant tissue with only the operculum remaining visible. N. (T.) capsiformis averaged 105.3 eggs/female. Much remains to be discovered concerning this fascinating and important group of predatory heteropterans. Knowledge about biology and taxonomy of this group is fundamental to developing future programs in integrated pest control.
