MORSE: ORTHOPTERA OF NEW ENGLAND. 395 
lights at night in swarms. In New England it seems to be 
more plentiful at high elevations, even on mountain tops 
(Mt. Ascutney, 3300 feet; Mt. Greylock, 3500 feet). In the 
vicinity of Boston less than ten per cent of examples are 
long- winged. 
This is by far our commonest species of Nemobius and it is 
plentiful in all parts of New England from extreme northern and 
eastern Maine to Nantucket and southwestern Connecticut. 
Extralimitally it occurs from Prince Edward Island to Mani- 
toba, and from Virginia to New Mexico, while another geographic 
race extends to the Gulf Coast and Mexico City. 
Adults begin to appear in early July in Connecticut, and late 
in July in Maine, and linger until killed by hard frosts. It is 
nearly ubiquitous, inhabiting a wide variety of situations, and 
often literally swarms at the edges of meadows and marshes and 
in the damper, densely grassed spots of pastures and fields. If a 
census were taken of our New England Orthoptera, this little 
Cricket would stand near the head in numbers. Though usually 
not accounted an injurious insect, it is undoubtedly responsible 
for a very considerable diminution of feed in our New England 
pastures. 
The song is a high-pitched, silvery or tinkling trill, often con- 
tinuous, sometimes broken irregularly or reduced to a chirp. Its 
quality and delivery vary widely and are doubtless affected by 
the size and emotions of the performer, the temperature, and the 
acoustic and other conditions of the time and place. It also 
sounds different according to the degree of sensitiveness of the 
ear of the hearer. At least, this seems the only way to account 
for the divergent statements of observers, who have attributed to 
several species songs unquestionably delivered by this one. It 
has been rendered by various authors as tiiiii or ti-ti-ti-ti-ti, 
creeeee, or creee-creee-creee and plee-e-e, plee-e-eee.
