This species is commonly taken in the pine regions of Long Island 
and New Jersey on the flowers and leaves of the white water lily. At 
Wyandanch, Long Island, a small number of specimens were taken once 
by Mr. Davis and myself on the flowers of the white daisy. However, 
this must be considered exceptional as the adjacent lake had been dredged 
and the insects not finding their natural food plant turned to the nearest 
flowers for food, the white daisy, which grows abundantly near the lake. 
At Wading River, Long Island, I took a few specimens from the flowers of 
Carex. Mr. Wenzel records it from several plants in New Jersey: "At 
Newfield, May 21, in numbers on the bloom of Oronimm aquaticum and 
easily disturbed during the heat of the day when they take to flight and 
rest on the leaves of the plant. At Bamber, June 9, in the flowers of 
Castalia odorata. At Newfield, June 18, the bloom of Orontium aquatictim 
being over specimens were found in the flowers of Nymphaea advena. 
At Hammonton, July 16, in numbers in the flowers of Castalia odorata.'' 
While this species is mostly found on strictly aquatic plants I do 
not believe that it breeds in these but probably in Carex. The species 
which are known to breed in aquatic plants have the pubescence of the 
underside denser, finer and shorter than in Uehecki. 
This is the Donacia pallipes Lac. wrongly placed as a synonym of 
D. aequalis in our recent list. The name pallipes, however, is used 
previously by Kunze for a European species. D! Uehecki is closely allied 
to megacornis but is rather more parallel and elongate in form, slightly 
more depressed, antennae annulate or black and hind femora with a 
small tooth which is not crenulate at its posterior margin. In form 
liebecki is somewhat like aequalis but the latter has a different prothorax, 
the sculpture of the latter and elytra is never coarse, the intercoxal 
process of the mesosternum is wider and the head is not strongly narrowed 
behind the eyes which are also slightly smaller.
