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

Keller 1, Michael Grant2, Bert Ebbers 3 and Robert Vande Kopple 2 ABSTRACT We report the discovery of the Federally endangered crawling water bee­tle, Brychius hungerfordi Spangler, in a new watershed in the northern lower peninsula f 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. The status of the crawling water beetle, Brychius hungerfordi Spangler, is a major concern given its restricted geographical distribution (USFWS 1994). Previously, Brychius hungerfordi adults had been reported from Michigan only in the East Branch of the Maple River (Strand and Spangler 1994, Spangler 1954) and the East Branch of the Black River (Wilsmann and Strand 1990). Brychius hungerfordi has also been discovered in Ontario, Canada in the North Saugeen River (Roughly 1991). Brychius hungerfordi is currently listed as endangered by the U.S. Fish and Wildlife Service (USFWS 1994). This paper documents the discovery of the Federally endangered crawl­ing water beetle, Brychius hungerfordi, in a previously unreported watershed in the Northern Lower Peninsula of Michigan. A total of four B. hungerf rdi adults were captured in the Carp River, Emmet County, Michigan (Twp. 39N, Rge. 4W, Sec. 32, s.w. 1/4) in August of 1997. The discovery of B. hungerfordi represents a new record for the beetle in this watershed. The Carp River is a first-order stream that drains the epilimnion of Paradise Lake. Th  s te is lo­cated on a glacial outwash plain approximately 10 km from the source. At this site, the river bed was cobble and sand. The Carp River flows through a second growth mixed deciduous forest fragmented by agriculture. The beetles were collected from a pool directly below a rime. Brychius hungerfordi was collected using a series of sweeps across the stream bottom using D-nets (30 cm diameter). Similar sampling effort at two upstream and two downstream sites yielded no other adult B. hungerfordi. This finding is consistent with previous reports of Brychius adults captured from rocky cob-IDepartment of Biological Sciences, Bowling Green State University, Bowling Green, OH 43403. 2University of Michigan Biological Station, Pellston, MI 49769. 3Great Lak s Ecosystems, P.O.

ABSTRACT 
We report the 
discovery of 
the Federally endangered crawling water bee­
tle, Brychius hungerfordi Spangler, in a new watershed in the northern 
lower peninsula f MIchigan. The site was found on the Carp River, a lake 
draining first-order stream. 
Nine 
water chemistry parameters were mea­
sured 
from 
three known locations of B. hungerfordi and from three sites 
where no B. 
hungerfordi 
have been found. Water from sites with known pop­
ulations of adult beetles showed low soluble reactive phosphorus, but were 
similar 
to 
other similar rivers in northern Michigan. 
The status 
of 
the crawling water beetle, Brychius hungerfordi Spangler, 
is 
a 
major concern given its restricted geographical distribution (USFWS 
1994). Previously, Brychius hungerfordi adults had been reported from 
Michigan only in the East Branch of the Maple River (Strand and Spangler 
1994, Spangler 1954) and the East Branch of the Black River (Wilsmann and 
Strand 
1990). 
Brychius hungerfordi has also been discovered in Ontario, 
Canada in the North 
Saugeen River (Roughly 1991). Brychius hungerfordi is currently 
listed 
as endangered by the U.S. Fish and Wildlife Service (USFWS 
1994). 
This paper documents the discovery of the Federally endangered crawl­
ing water 
beetle, Brychius hungerfordi, 
in a previously unreported watershed 
in the Northern 
Lower 
Peninsula of Michigan. A total of four B. hungerf rdi 
adults were captured in the Carp 
River, 
Emmet County, Michigan (Twp. 39N, 
Rge. 4W, Sec. 32, s.w. 1/4) in August of 1997. The discovery of B. hungerfordi 
represents 
a new record for 
the beetle in this watershed. The Carp River is a
