What is "sarcotoxin"

n. Any of a group of antibacterial proteins found in the flesh fly (genus ''Sarcophaga'').

Sarcotoxins are a group of antibacterial proteins present in the flesh fly belonging to the genus Sarcophaga. The proteins are present in the haemolymph of the fresh fly. The first protein, called sarcotoxin 1A, was discovered in 1983 from Sarcophaga peregrina by Masayuki Okada and Shunji Natori at the University of Tokyo, Japan.

Sarcotoxins are sometimes/often classified as cecropins since they are found in insects.
