OFF with their heads! In the competition for fire ant hosts, is Pseudacteon curvatus delivering the knock-out punch?
In 2002, the species were not in competition for resources and were found in large numbers in their respective locations. However, the 2010, 2012-2013 data were collected with the species coexisting in the same geographical locations. The data shows that there has been a dramatic shift in P. tricuspis numbers while in competition with P. curvatus for resources, making P. curvatus the predominant fly species. There has also been a major shift in diurnal activity of P. curvatus when all three species are in competition for resources.
