Explanation of Names
Messatoporus discoidalis (Cresson, 1872)
from the New Latin discoidālis ('discoidal')
Known larval hosts include Auplopus mellipes mellipes, Ageniella conflicta, and Phanagenia bombycina (Pompilidae).(1) Additional host records for Ceropales maculata fraterna are considered by Townes as misidentified records that are "doubtless cells of Auplopus or Phanagenia."(2)
