Graptostethus trisignatus is recorded from the plains of Darjeeling district, West Bengal, for the first time, feeding on the fruits and seeds of the understorey climber Argyreia sp. in sal forest. It is suggested that the association of the lygaeid with the thick leaf litter on the forest floor indicates a possible role as a secondary decomposer in the detritus food chain. Adults, immature stages and development period are described. It was noted that adults kept in culture without leaf litter did not lay eggs.
