    There is significant variation in the distribution of Diptera (true flies) that contribute to decomposition and are of forensic importance. In an effort to study this distribution, it is necessary to attract these species of Diptera via an artificial trapping method. However, there is no definitive answer to the bait that should be used to collect the greatest quantity of Diptera of forensic importance or the richest diversity. To understand the differences in baits for Diptera traps three butterfly traps were placed in three different areas of the USDA-ARS property in Kerrville, Texas. Traps were set in the morning with the same bait. Contents of the traps were then collected at the end of the day, frozen, and later identified. The specific baits used were decomposing beef liver and catfish filets. Diptera were collected off of roadkill, and compared. This was done three times a week for six weeks in June through July. Eight Calliphoridae species were collected, including Cochliomyia macellaria, Lucilia mexicana, and Chrysomya rufifacies. In total, 697 dipterans were collected, 588 from fish-baited traps, nine from liver-baited traps, and 100 from roadkill. While statistical analysis was not possible, there was a clear descriptive difference in the amount each bait attracted. Catfish was the more attractive bait and captured greater species diversity as compared to beef liver.
