Occurs on the flowers and leaves of the yellow water lily. 
The males of pahnata can not be mistaken for any other species on 
account of the strongly and curiously dilated first joint of front tarsi. 
The females, however, are close to piscatrix and to texana. The latter, 
however, is of a little stouter form and has the middle tibiae not dilated 
internally at apex into a short tooth-like process. The females of 
piscatrix are less elongate and have generally, in the typical form at least, 
shorter and stouter antennal joints and legs, the intermediate femora 
more robust and scarcely clavate and the last ventral segment is more or 
less distinctly produced at apex into a short, laminate process. 
DoNACiA TEXANA Crotch. 
Similar in form to pahnata but slightly shorter and a little more 
robust; color variable, head and prothorax metallic green to cupreous, 
elytra blue, purple or entirely green; antennae mostly dark with green 
metallic tint, occasionally a few joints narrowly reddish at base; legs 
pale, femora in apical half or more entirely metallic green, tibiae and 
tarsi also more or less metallic green towards apex; body beneath pale, 
at sides generally darker. 
Head feebly constricted behind the eyes which are rather large 
and moderately prominent; surface densely and finely punctate; median 
line generally deeply impressed; antennae extending to or beyond the 
middle of elytra, joints rather narrow and elongate, third joint longer 
than the first. 
Prothorax generally not quite one half wider at apex than long; 
anterior angles distinct, generally not prominent; posterior angles 
prominent; lateral tubercle more or less distinct; anterior transverse 
impression generally distinct; posterior sub-basal impression rather 
broad and shallow; median impressed line fine and more or less distinct; 
sides scarcely converging behind and at most feebly sinuate; surface 
dull or feebly shining, alutaceous with a few, fine punctures on the disk. 
Elytra twice as long as wide at base; strial punctures rather small 
and slightly finer towards apex; intervals distinctly wider than the
