Chorophilus nigratus LeConte. Only a few of these were seen on the 
bog. Inland they were present in great numbers. Several were observed 
while capturing the leaf hoppers and small flies. 
REPTILIA 
Chrysemys bellii Gray. These turtles are often seen basking on logs 
which stick up out of the water. They are very easily alarmed and quickly 
scramble off to hiding places in the mud and vegetation at the bottom of 
the bog. 
Aves 
Agelaius phoeniceus phoeniceus Linnaeus. These black birds feed on 
the wild rice which grows on the bog. During September and October 
they appeared in great flocks. 
Butorides virescens virescens Linnaeus. One was observed on the 6th 
of August. They are not very common in this locality. 
EVERYDAY LIFE ON THE BOG 
Animal life on a bog is an almost ceaseless round of activity. 
On a hot summer day alert dragon flies are constantly winging 
here and there in pursuit of small insects which they either devour 
instantly or carry to their stations at the top of some dead reed. 
At times one will sail down to the water’s surface where she mo- 
mentarily dips her body to release an egg. Nowhere can more 
striking coloring be found than among these graceful creatures. 
Here is one with a body of bright green and with wings almost 
transparent; a second later another comes with a body of bril- 
liant red, a third of shiny black, and finally another with a body 
of bluish gray. 
In this association, but nearer the shore and almost hidden 
among the reeds, are the damsel flies. Lestes, the most common, 
lightly steals about, the female forming a graceful arch with her 
body as she places her eggs one by one in the plant stems. 
Numerous species of smaller insects — such as brightly colored 
flies, beetles, grasshoppers, and small moths and butterflies — fly 
about among the reeds and grass. 
In the low vegetation are several species of snails and ground 
beetles, many of them buried in the cool, damp bog. 
Far out in the marsh the occasional croak of a frog or the splash- 
ing of a turtle is heard. And every now and then the red winged 
black bird flies over the marsh giving his flute-like ok a lee.
