Explanation of Names
Dasymutilla quadriguttata (Say 1823)
Females: Mesosoma is longer than broad with a scutellar scale. Presence of linear tubercles on the posterolateral angles of the head. Coloration and number of maculae/spots on the second tergite varies.
Males: A pit filled with dense setae present on the second sternite. Coloration doesn't seem to vary much (all black or very dark red except for the orange integument on the second tergite).
Males are hard to identify from photos, as they can have the same coloration as D. bioculata and D. vesta (entirely black except for the orange/yellow macula on the second tergite).
