Parcoblatta Uhleriana
''Parcoblatta uhleriana'', the Uhler's wood cockroach, is a species of ''Parcoblatta'' native to the United States and Canada. It is a forest species also found in disturbed and urban environments. The male of the species flies freely, while the female does not fly. Description The male ''Parcoblatta uhleriana'' is a mostly uniform pale brownish-yellow, with slightly darker tegmina (outer forewings). It is relatively slender, with a broad head, and brownish stripe from the middle of its eyes downward.

Parcoblatta Pennsylvanica
The Pennsylvania wood cockroach (''Parcoblatta pensylvanica'') or Pennsylvanian cockroach is a common species of cockroach in eastern and central North America. Description Males are dark brown; the sides of the thorax and the front half of the wings are margined with yellow. Adult males are fully winged, while females have conspicuous wing pads (actually short wings like that of the female oriental cockroach), which are functionless. Wings of the male are longer than its body, while wing pads of the female cover only one-third to two-thirds of the abdomen. The males fly swiftly but do not have the ability to sustain themselves in the air for long periods. Habitat and ecology The species occurs in open, timbered areas with little ground cover. According to entomologist Fred A. Lawson, it is "often seen on tree trunks and lower branches of oaks and elms after dark." Nymphs and adults are also found outdoors beneath loose bark in woodpiles, stumps, and hollow trees. Brought i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parcoblatta Fulvescens
''Parcoblatta fulvescens'', the fulvous wood cockroach, is a species of cockroach endemic to the United States and possibly Canada that measures around long. Description The male ''Parcoblatta fulvescens'' is relatively slender, has long tegmina (outer forewings), and is slightly longer than the female. It is a mostly uniform pale brownish-yellow, with sometimes darker pronotum (the plate behind the head) and legs, and usually dark brown cerci (the pair of appendages on its rear-most segment).

Parcoblatta Divisa
''Parcoblatta divisa'', the southern wood cockroach, is a species of cockroach native to the United States. Due to morphological similarities, it was earlier considered a subspecies of '' Parcoblatta pensylvanica'', termed ''P. pensylvanica divisa'', found in the lower part of the southeastern United States. In particular, males of the two species are different from others of their genus in that the seventh dorsal abdominal segment conceals almost all of the eighth segment (more pronounced in ''P. pensylvanica''), and share a specialialized character of protuberances of the median segment. (The article comprises the whole issue.) Individuals of the species are typically dark in color, but a pale morph is uniquely found in Alachua County, Florida, with no dark individuals among hundreds of specimens collected from the location. Distribution The distribution of the species includes the eastern and southeastern United States, including Alabama, Arkansas, Delaware, Florida, Geor ...

Parcoblatta Caudelli
''Parcoblatta caudelli'', Caudell's wood cockroach or Caudell's wood roach, is a species of cockroach Cockroaches (or roaches) are a Paraphyly, paraphyletic group of insects belonging to Blattodea, containing all members of the group except termites. About 30 cockroach species out of 4,600 are associated with human habitats. Some species are we ... native to the United States. The male of the species has a pale clay-yellow head, underside, and legs. The back of its abdomen, pronotum disc, occiput (X), and a transverse bar in the middle of its face are a brownish-yellow. Tegmina are fully developed, and are slightly wider than the pronotum. It has long, thin cerci. While the species is the smallest of the pale brown species of the genus ''Parcoblatta'', its abdomen is modified like ''Parcoblatta lata'', the largest of the genus. Fred A. Lawson wrote in 1967 that the female is fully winged and capable of flight, a trait he stated was unique among the ''Parcoblatta'' species i ...

Parcoblatta Americana
''Parcoblatta americana'', the western wood cockroach, is a species of wood cockroach that occurs in Mexico and the western United States. Description The species has significant size and color variation, thought to be due to environmental conditions, particularly the effect of aridity. The male of the species has normal, fully developed tegmina and wings, and a tuft of hairs on the back of its middle abdomen. The general coloration in the male can vary from shining dark brown or blackish to a pale yellowish to slightly reddish tan. The tegmina are translucent in all colorations, and the ocelli (simple eye spots) are a yellowish tan. Females of the species have very greatly reduced tegmina, represented by lobe-like lateral pads, and no hind wings. The female general coloration ranges from a shining reddish orange or brown, slightly darker on the back of the abdomen, to a shining dark brown, or shining black with blackish brown underparts. The ocelli are tannish in all colorati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parcoblatta Notha
''Parcoblatta notha'', the Arizona wood cockroach, is a species of wood cockroach that occurs only in the southwestern US state of Arizona.

Parcoblatta Desertae
''Parcoblatta desertae'', the desert wood cockroach or desert cockroach, is a species of ''Parcoblatta'' endemic to the United States state of Texas. Description The tegmina (outer forewings) and inner wings of the male are normal and fully developed, while in the female, the tegmina reach only the base of the median abdominal segment, and the inner wings are small, vestigial pads. Male coloration is a generally dull, light ochre color, with blackish brown eyes, semi-transparent dull ochre tegmina, and hyaline (glassy) wings. Female coloration is described twice in Morgan Hebard's 1917 description, separately describing the female type specimen, which he noted was smaller and paler than three other female specimens, which he thought was probably due to decidedly reduced vegetation in the area from which it was taken. The female type specimen was described as having a dull ochre-orange coloration on the head, pronotum, and underside of the abdomen, with sides of the pronotum ...
