This is the most abundant and generally distributed Tree- 
cricket in New England. While apparently most at homo in the 
weedy jungles of pastures and along woodland edges, composed of 
asters,goldenrod,everlasting, St. John's- 
wort, Joe-Pye-weed, etc., it is also com- 
mon on wild carrot in mowing-lands, 
among raspberry and blackberry 
bushes, in young birch thickets, in 
bush-grown pastures, and amid a great 
variety of other vegetation. It is often 
very plentiful where it occurs, and its 
song is heard almost continually in the 
afternoons of late summer and autumn. 
This is a soft, continuous trill, much 
higher in pitch than that of Oe. niveus, 
closely resembling that of Oe. nigricornis 
but sometimes seeming to lack the vol- 
ume and intensity of the song of that 
species. It varies so much individually 
and according to temperature and 
acoustic conditions of the environment 
that it is not always possible to say 
with certainty which is which until the 
singer is captured. 
This species oviposits chiefly in such 
weeds as goldenrod, wild carrot, aster, 
etc., usually placing the eggs in irregular 
rows made up of several groups of from 
two or three to half a dozen, in the pith ^ „ ^
