Differentiation between Lucilia cuprina and Hemipyrellia ligurriens (Diptera: Calliphoridae) larvae for use in...

Lucilia cuprina and Hemipyrellia ligurriens are forensically important blow flies in many countries. The immature stage, in particular the third instar, of both species are generally similar in morphological appearance. In this study, the use of three main characteristics, the posterior spiracle, the dorsal spines between the first and second thoracic segments, and the cephalopharyngeal skeleton, allows for identification of both fly species, with the number of papillae on anterior spiracle being a supportive characteristic in some cases. Comparison of these characteristics is illustrated in detail.
