Exploring the evolutionary history of a novel trait in Sepsidae.
Novel traits allow us to investigate the evolutionary mechanisms that lead to the gain of new morphological structures or physiological functions. The novel abdominal appendage in male sepsid flies (Diptera: Sepsidae) has a complex evolutionary history of primary gain, loss, and regain which we explore using fluorescent microscopy to compare the size, volume, and number of cells in the histoblast cell nests that produce the appendage during pupation across six genera including an ancestral outgroup which describe evolutionary history of the appendage. Data was also collected in females which lack the appendage. Nest size and cell number in each segment differs significantly between species and male and females.
