     Common through most of the eastern USA to the S Texas coast. The South Florida population has been named texanus (as in Tyler, Brown and Wilson); it has  also been described as a new ssp, fakahatcheensis (R Gatrelle, 2000.) The problem here (as I see it) is that there is a belief that the type of texanus actually is from S Florida (its data are not available), and matches the new types of fakahatcheensis. Whether the S Texas specimens are truly different from nominate troilus or the new fakahatcheensis is not known to me.  Make your own decisions. The point is, the S florida specimens are clearly and consistently different. This is a good example of why exact collecting data are so important...
