Wasp Mantidfly at Backus Woods, Norfolk on 3 July 2010 The Wasp Mantidfly is not only the most widespread species but the easiest to identify. It's fairly large and its body is striped brown and yellow similar to that of many species of wasp. The other three Canadian species look different from the Wasp Mantidfly but are quite similar to each other and require very good photos, preferably showing close-ups of the pronotum and the wings. This observation is clearly one of the remaining three species. On figure 2, the pronotum is visibly smooth (lacks "numerous short setae over its entire length") which means it is one of the two Dicromantispa species. The separation of those two species is done by the presence/absence of dark spots on the "wing tips and some cross veins of radial cells", which this specimen lacks. That puts the identification as Dicromantispa sayi. This is exciting because, according to the paper referenced above, this would be a (known) range extension for the species in Ontario, which, based on examined
