Comparative data for dance fly eye morphology and female ornamentation

These data were collected as part of a comparative study of the relationship between female ornamentation and sexual dimorphism in eye morphology. Data come from specimens collected in the field in Scotland near Loch Lomond in the summers of 2009, 2010, and 2011 as well as the summer of 2012 near Glen Williams in Ontario, Canada. The repository contains raw image files including information on magnifications at which these were taken, excel spreadsheets of morphological measurements taken from these images, a dataset from search of Collin’s (1961) key to the Empidinae for reports of sexual dimorphism and exaggerations of male eye morphology, and an R notebook file detailing the analytical steps taken., Flies were caught from mating swarms or when resting on vegetation using sweep nets. Differences in eye morphology were quantified from nail varnish casts of the compound eyes of males and females. Female ornamentation was quantified as the total leg area of the four posterior legs of males and females., Comparative analysis was performed using a phylogeny published in: Murray et al., 2020 Competition for access to mates predicts female-specific ornamentation and polyandry. Evolution. As well as a phylogeny available in this repository (folder \"phylogenetics\").

This repository contains data for comparative analysis of morphology in dance flies.
We have collected data on descriptions of female ornamentation from the taxonomic key by Collin (1961)

The data were analysed and results are presented in a manuscript:
