Aedes thibaulti in northern New Jersey.
Aedes thibaulti Dyar and Knab occurs from southern Louisiana, USA, to Ontario, Canada, but has an exceptionally patchy distribution over much of its range. Typical breeding habitat for this univoltine species includes cavities at the bases of trees growing in low-lying swampy areas or dark recesses within the root balls of upturned trees. Larvae have never been collected in the northeastern portion of the range, but adult records suggest that breeding populations are present. The lack of low-lying swampland in northern areas where adults have been collected suggests that the breeding habitat for this species may not be as specific as previously believed. On April 20, 1997, we collected Ae. thibaulti larvae from the flooded cavity of a red maple tree (Acer rubrum) growing next to a temporary snow pool in northern New Jersey. Larvae persisted in this habitat until mid-May when the cavity dried completely. The collection suggests that Ae. thibaulti is a cavity breeder in the northern portion of its range, but is able to utilize cavity habitats associated with temporary pools in dry forested areas.
