Sex-ratio of Miridae (Hemiptera) taken via UV light-traps in Arkansas, USA.
We determined the sex-ratio of 1,095 plant bugs (Hemiptera: Miridae) taken from 60 individual UV light-trap samples in Clark County, Arkansas over a two year period. We found that of the 21 taxa in which a sex-ratio determination could be made, 61.9% of them (13 of 21) contained a majority (over 50%) of males. Three taxa were exclusively represented by males, while two taxa were exclusively represented by females. Although taxa dependent, our data indicate that male mirids are, in general, more frequently encountered in UV light-traps. However, contrary to the notion that sparked this study (see herein) light-trap content was not represented vastly to exclusively by male individuals as the sex-ratio of the cumulative data was 62.47% males (684) and 37.53% females (411)
Distribution, Habitat, and Life History Aspects of the Shrimp Crayfish, Faxonius lancifer (Hagen) (Decapoda: Cambaridae) in Arkansas
The Shrimp Crayfish, Faxonius (formerly Orconectes) lancifer (Hagen) is an uncommon, although widespread, crayfish in Arkansas. This species is herein documented from 19 counties of the Gulf Coastal Plain physiographic region. Between 1974 and 2017, we made 344 collections throughout the 75 counties of Arkansas, of which 22 (6%) yielded 163 specimens of F. lancifer. Thus, from these collections, plus 10 unpublished collections of Reimer (1963), and one collection from G.L. Harp, a total of 34 collections of F. lancifer are now known from the state. Faxonius lancifer ranged from uncommon (1 specimen) to locally abundant (39 specimens) at these collecting localities. With regard to conservation status, F. lancifer should be considered as Currently Stable due to its widespread distribution and general abundance in Arkansas
