Description

Neuropteran insects display a phenomenon called distance segregation during male meiosis I, where the X and Y chromosomes are unconnected from prometaphase I through anaphase I. Here we investigate chromosome number and patterns of chromosome segregation of a previously unstudied Neuropteran: the green lacewing, Chrysoperla rufilabris (Burmeister, 1839). Testes of male C. rufilabris were isolated and prepared following a chromosome squash method. Living meiosis I spermatocytes were also imaged. The data revealed a chromosome number of 2n=12 in males (2n=10+XY) and evidence of distance segregation of X and Y chromosomes in meiosis I spermatocytes.
