Signal fly, Scholastes sp. (Diptera: Platystomatidae) was observed associated with
animal carcasses in Malaysia. The first observation was on a monkey carcass, which was killed
by using a handgun and immediately placed in a forested area in Gombak, Selangor while the
second observation was on a pig that died of natural causes and whose carcass was placed in an
oil palm plantation in Tanjung Sepat, Selangor. Both animal carcasses were visited by Scholastes
sp. flies during the fresh decomposition period. However, the role Scholastes flies in the
decomposition process remains unknown. In this paper, we report the occurrence of Scholastes
sp. on animal carcasses in Malaysia for the first time.
