This structure is raised around the cap in a stable ring in Pentatomidae, but tends to project from the inner side of the shell in Acanthosomidae, Cydnidae, Scutelleridae, and Thyrocoridae (Javahery 1994; Candan 1997; Candan and Suludere 2003).

Richmond (1962, 1968) did not record members of Blissidae, Geocoridae, Largidae or Cydnidae (the two species of the latter present in his 1962 list are actually members of the family Corimelaenidae) from Horn Island, all of which were found on Point Clear Island, although none of the species was common here.
Schuh and Slater (1995) mention that the hemipterans Cydnidae, Lygaeidae, Miridae and Nabidae are associated with ants as their predators or imitators; besides, the Membracidae where some species are attended by ants.
Constant (2007) added several records including collection data from 10 species of Cydnidae that were taken in pitfall traps baited with human excrement or dead fish, but questioned whether the bait attracted them because cydnids also can be found in unbaited pitfall traps.
Sin embargo, hasta el presente, los grupos de insectos mas utilizados en reconstrucciones ambientales son los coleopteros (familias Carabidae, Scarabaeidae, Cydnidae, Chrysomelidae y Coccinellidae) y los quironomidos (orden Diptera, familia Chironomidae).
Although subsocial behavior has been reported for a number of families within the order, reports of parental care that extends to providing nymphs with a food source have only been recorded for 4 species belonging to the Cydnidae, subfamily Sehirinae; and to one species of the related Parastrachidae, despite the fact that the biology and behavior of many species of Cydnids are unknown because most of the species live underground.
Cydnidae is monophyletic only in the morphological analysis, but in the molecular and combined ones it is paraphyletic, in particular because of Corimelaenidae and Thaumastellidae.
