Teleogryllus mitratus ( sometimes called Gryllus mitratus) is a cricket worthwhile for commercial production that seems overlooked because of it's size. To see pictures of adults & some sound recordings search the name at http://orthoptera.speciesfile.org
As I pull together my notes will detail in further comments why this is an interesting cricket for commercialization. It's nickname is the "oriental garden cricket" & a founder population can be wild collected (so will get to trapping too).
For now here is a link to the adult T. mitratus protein amino acid breakdown if considering cricket meal as a feed supplement ingredient. Data is dependant on variability of tested individuals, so on average the adults are 54% protein (range tested of 46-62% protein). And will add here that for fat content the average is 25% lipids (range tested of 23 to 26% fat). All individual amino acid values in free full text on-line are given as ppm from report titled: "Protein isolation from cricket Gryullus mitratus."
