Cases of maternal care and egg guarding were observed and photographed
in bugs of the family Tessaratomidae. Females of one still undescribe
d species of Pygoplatys from Doi Inthanon, Thailand, and of Pygoplatys
acutus from Borneo are carrying their young larvae on the venter. The
egg guarding was also observed in Pygoplatys acutus from Kepong, Peni
nsular Malaysia. It seems, that maternal care is a characteristic beha
vior in bugs of the genus Pygoplatys.
