New Distribution Record for the Endangered Crawling Water Beetle Brychius Hungerfordi (Coleoptera: Haliplidae) and Notes on Seasonal Abundance and Food Preferences

The Federally beetle, Brychius hungerfordi, has been discovered at a new location in Northern Lower Peninsula of Michigan. We also report preliminary data on a seasonal variation in relative abundance and on its possible food plants

Size Estimate of a Local Population of Brychius Hungerfordi (Coleoptera: Haliplidae)

Much of the natural history of the endangered crawling water beetle, Brychius hungerfordi, is unknown. Population estimates have only been surmised. We have measured, using a mark and recapture technique, a localize population of the beetle in a pool on the East Branch of the Maple River, Emmet County, Michigan. The average population during July 2001 was found to be 1052 individuals with a range of 43 (highest estimate – lowest estimate). A three-year study of the relative abundance of the beetle in the same pool suggests that the population has remained relatively constant

New Record for the Endangered Crawling Water Beetle, \u3ci\u3eBrychius Hungerfordi\u3c/i\u3e (Coleoptera: Haliplidae) in Michigan Including Water Chemistry Data

We report the discovery of the Federally endangered crawling water beetle, Brychius hungerfordi Spangler, in a new watershed in the northern lower peninsula of MIchigan. The site was found on the Carp River, a lake draining first-order stream. Nine water chemistry parameters were measured from three known locations of B. hungerfordi and from three sites where no B. hungerfordi have been found. Water from sites with known populations of adult beetles showed low soluble reactive phosphorus, but were similar to other similar rivers in northern Michigan
