Calosoma (Calodrepa) wilcoxi LeConte, 1848

Calosoma Wilcoxi LeConte, 1848: 446 (described from Nov. Eboraco (= New York); syntype: Texas and Middle States (Md., Del.,N.Y., N.J., Pa., Conn.?, R.I.?); Museum of Comparative Zoology, Harvard University, Cambridge, Ma)
Calosoma wilcoxi Breuning, 1927: 165
Calosoma (Calodrepa) wilcoxi Lapouge, 1932: 405
Calodrepa wilcoxi Jeannel, 1940: 78
Calosoma (Calodrepa) wilcoxi Gidaspow, 1959: 251
Calosoma (Calosoma) wilcoxi Erwin, 2007: 107

Length 17-22 mm. C. wilcoxi, on average, has smaller dimensions when compared to all the other species collected in Calodrepa. Superficially, because of the color and shape of the body, may seem like a small C. scrutator but is distinct because it is the only species of the group that has the metatrochanters bearing a seta and straight, or at most slightly arcuate, male mesotibiae.
According to Gidaspow (1959: 251) and Erwin (2007: 107), C. wilcoxi ranges across most of the United States from the Atlantic coast to California but it is more abundant in the eastern states. It is found in Ontario and Quebec (in this last case probably only as an occasional visitor) down to Texas, but it has never been recorded from Mexico. Moreover, Following its importation as a potential agents of biological control in Hawaii, C. wilcoxi has been cited as part of the entomological fauna of the Islands.

Notes: Winged, diurnal as well nocturnal and attracted to light at night. Adults in great number were observed while feeding upon species of Geometrid caterpillar. Active individuals were captured from April to June (on the basis of the material examined), that is also the coupling period, or all year round according to Erwin (2007: 107), but adults sometime are found overwintering in small cavities in the ground.
A brief description of larval stages can be found in Burgess & Collins (1917: 41).
