List compiled primarily from FLOW (Bourgoin 2013), also Metcalf (1957) and an unpublished list by Lois O’Brien.

Economic Importance:


Plant associations:

Paradascalia edax – “Laccodesmia and the related mesquite (Van Duzee 1923: 197” (possibly meant Lygodesmia (Asteraceae), but this is not related to mesquite),Prosopis L. (mesquite, Fabaceae), Larrea tridentata (DC.) Coville (creosote bush, Zygophyllaceae), Sideroxylon L. (bully, Sapotaceae), “pertyle” (and ‘other plants’).

Hosts from Van Duzee (1923), Wilson et al. (1994); plant names from USDA PLANTS or Tropicos.  See also any hosts listed on FLOW.


(Paraphrased from Metcalf’s (1938) key, which in turn is modified from Melichar (1923)).

Sutural angle of tegmina not prolonged, Tegmina ‘not especially’ narrowed distally, tegmina bearing 2 apical lines, broadly curved and parallel to distal margin, 3 carinal lines on “forehead”

Paradascalia is a Neotropical genus.  One species of Paradascalia can be found in southern California, but it is primarily a Mexican species.  Among North American Selizini, this is the only genus where the forewings are slightly narrowed, rather than forming an elongate projection, as in Cyarda and Mistharnophantia.  Paradascalia is much more similar to Dascalia Stål, which tends to be more elongate and has the subapical lines of the tegmina sinuate.  There is a flatid I have seen from far southern Texas that may be in this genus or one of the similar Mexican taxa.

None informative.  Paradascalia at FLOW.  Paradascalia is present at Discover Life here, and at Encyclopedia of Life hereParadascalia is not present on Bugguide


Paradascalia like many flatids can be taken by inspection, sweeping/beating or sometimes at lights.  Van Duzee (1923) described P. edax from 109 specimens, so it may be common where it occurs.

Molecular resources: 

None. Paradascaila is not in GenBank; or in Barcode of Life. (update: There are a lot of flatid genera on barcode of life, but Paradascalia is not one of them).
