This behaviour is believed to enable it to escape the intense interspecific competition which can occur between dipterous larvae within carrion. Such escape is necessary as this fly species has been thought to have reduced competitive ability, resulting from its evolutionary progression towards parasitism. In the work reported here, the attraction of L. sericata to carrion bait at different stages of decomposition (fresh to 28 days old) was investigated in the field. Trials were run over three years, with carrion bait presented in the presence and absence of sodium sulphide. Decomposition had a significant effect on the numbers of L. sericata caught; more decomposed bait caught greater numbers of L. sericata than fresh bait. However, this effect was not apparent if sodium sulphide was added to the carrion. With sodium sulphide added, there was no significant difference in the attraction of female L. sericata, regardless of bait age. There was no general relationship between carrion bait age and the number of female L. sericata caught in different stages of ovarian development. The present data, therefore, suggest that L. sericata does not act exclusively as a pioneer species. Furthermore, this work suggests that, if used with sodium sulphide, the stage of carrion bait decomposition does not significantly modify carrion bait attractiveness.
