Oedipoda haldemanii S.H. Scudder, 1972. Type locality: Platte River, Nebraska
Aedipoda haldemanii C.R. Dodge, 1872. Misspelling for "Oedipoda".
Hippiscus haldemanii (S.H. Scudder) S.H. Scudder, 1876
Oedipoda paradoxa Glover [non Thomas], 1878. Type locality: unknown (perhaps based on a specimen from near Ogden, Utah?); likely the illustration was from specimens sent to Glover by Thomas under the name of Oedipoda paradoxus, and also it is likely Thomas' original description of O. paradoxus was a mix of Xanthippus corallipes & Pardalophora haldemanii (the wtitten description actually fits the later species best!); however, Thomas' lectotype specimen is apparently referable X. corallipes, making Thomas' H. paradoxus a synonym of X. corallipes. Apparently Glover's use of the name cannot be directly tied to Thomas' name, but they are probably one and the same; Glover's original publication/illustration needs to be consulted.
Hippiscus (Pardalphophora) haldemanii (S.H. Scudder) Saussure, 1884
Hippiscus (Pardalphora) nanus Saussure, 1884. Type locality: Illinois
Hippiscus (Xanthippus) tigrinus S.H. Scudder, 1892. Type locality: West Point Nebraska
Pardalophora haldemanii (S.H. Scudder) W.F. Kirby, 1910
Xanthippus tigrinus (S.H. Scudder) W.F. Kirby, 1910
Very similar to Xanthippus corallipes, but somewhat "smoother" looking; pronotum with median carina fairly evenly elevated and usually only cut once; hind femur slender (not widened strongly along lower margin); hind tibia and inner face of hind femur more often yellow or orange than red, inner face only rarely darkened, and then usually only appearing washed with dark, not boldly so. Wings yellow, orange, red, or pink (only yellow X. corallipes in most areas where the two occur together).
Primarily prairies of west from southernmost Canada to Oklahoma, the Texas Panhandle and ne. New Mexico, and from Michigan, Illinois, Missouri, and Arkansas to almost or just barely the east base of the Rockies.
Also, in Great Basin near west base of high central mountains of Utah and into se. Idaho (often associated with old Lake Bonneville shoreline deposites).
Open grasslands, especially gravelly patches in prairies on hilltops and hillsides, and in sandhills areas, but it is a common species, not too picky as long as the habitat is relatively dry, has grass, and is open and sunny.
Adults mostly in the later half of spring, most common in June-July in the north and May-June in the south. Adults are rarely seen anywhere after July.
Mostly grasses, but will eat a wide range of herbaceous plants, and occasionally other insects.
overwinters as nymphs; matures in spring; adults usually most common in June.
This "species" intergrades with Pardalophora saussurei at roughly the latitude of the south border of Kansas and Colorado, and most specimens from southern Kansas, southeastern Colorado, as well as many from northernmost Oklahoma, and the north end of the Texas Panhandle are intermediate in nature. These tend to have the fastigium a bit more produced, the pronotum more acute at the hind angle, the hind femur wider below, the inner face of the hind femur variably bluish to solid yellow/orange, etc. Biologically P. saussurei is a southern subspecies of P. haldemanii, but it is treated as a species in publications.
Often attracted to bright lights at night.
