Leptocorisa acuta are crepuscular, active during the early morning and late afternoon. During the heat of midday, they leave the rice crop in search of wild grassy areas. These bugs also seek shelter during dry months . Leptocorisa acuta is known to transmit Sarocladium oryzae and Sarocladium attenuatum (fungi), the cause of sheath rot disease. Sheath rot disease damages the panicle (branched arrangement of flowers) of the rice plant, which causes the plant to produce under-developed or damaged rice grains. In severe cases, the infected plant may not produce rice grains.

Leptocorisa acuta (Thunberg) can be found on many crop plants in the family Poaceae (grasses), especially rice, and is a reported pest of economic significance in rice-producing countries like Indonesia, Malaysia, and Brunai darussalam.
