CULICINI 117<br />
anteantennal tuft long and multiple. The abdomen stout ; lateral<br />
hairs on <strong>the</strong> first to fifth segments double, on <strong>the</strong> sixth, single. Eighth<br />
segment bears a lateral comb <strong>of</strong> many scales in a triangular patch.<br />
Anal segment longer than wide; dorsal plate reaching fully two-thirds<br />
<strong>of</strong> <strong>the</strong> way down <strong>the</strong> sides; dorsal tuft consists <strong>of</strong> a long hair and a<br />
brush on ei<strong>the</strong>r side; ventral brush well developed with short tufts<br />
preceding <strong>the</strong> barred area to near <strong>the</strong> base. Anal gills ensiform, as<br />
long as or sometimes much longer than <strong>the</strong> segment. -Air-tube taper-<br />
ing, three times as long as wide; pecten reaching just beyond <strong>the</strong><br />
first third <strong>of</strong> <strong>the</strong> tube; tuft large, situated beyond <strong>the</strong> pecten.<br />
This species is widely distributed over <strong>the</strong> United States<br />
from <strong>the</strong> Gulf <strong>of</strong> Mexico to Sou<strong>the</strong>rn Canada and west to <strong>the</strong><br />
Pacific Coast in its nor<strong>the</strong>rn range.<br />
It is one <strong>of</strong> our most common Aedcs species. The larvae are<br />
found in early spring, breeding in woodland pools filled by<br />
melting snows or spring rains. In general <strong>the</strong>y prefer pools<br />
with a bottom <strong>of</strong> dead and decaying leaves though <strong>the</strong>y are<br />
found in roadside puddles, spring fed pools, cranberry bogs,<br />
pools in open sphagnum bogs, wooded swamps and open meacl-<br />
ows. The species hibernates in <strong>the</strong> egg stage and <strong>the</strong> young<br />
larvae are found when <strong>the</strong> ponds are still ice covered. 1Vhe<strong>the</strong>r<br />
this species is single brooded or has a second brood in a season<br />
is still doubtful. Undoubtedly <strong>the</strong> great majority <strong>of</strong> eggs hatch<br />
in early spring, <strong>the</strong> adults appearing in maximum abunclance<br />
in late h!lay and early June.<br />
At Ithaca I have obtained <strong>the</strong> larvae in considerable numbers<br />
in mid-summer from artificial pools made in dry surfaced<br />
sphagnum bogs. Whe<strong>the</strong>r <strong>the</strong>se late appearing larvae are from<br />
eggs laid <strong>the</strong> previous season or from recently deposited eggs<br />
is not known. The adults do not wander far from <strong>the</strong>ir larval<br />
habitat. They readily attack especially towards <strong>the</strong> evening and<br />
dften prove a serious pest in woodlancls and forests. The)<br />
have not been taken in houses.<br />
