The Meduxnekeag’s Appalachian Hardwood Forests have a unique ecology extending well beyond the trees and flowers and ferns that are found there and not elsewhere in New Brunswick.
In the summer of 2004, a team of entomologists – Reginald Webster, Kate Bredin, and Jim Edsall – spent about two weeks in July, August and September at the Meduxnekeag Valley Nature Preserve collecting insects and documenting biodiversity. Their survey found a number of species at Bell Forest, Leonard Woods and Wilson Mountain which had not been recorded in New Brunswick. Some of these were new records for the Maritimes, and one is believed to be a first for Canada.
These new species records include
The Lepidoptera are probably one of the best known insect groups in New Brunswick in terms of distribution and habitat associations. Several species that are likely closely associated with rich hardwood forests were found during this study. These are Bomolocha deceptalis, Bomolocha madefactalis, and Catocala neogama, which use either Basswood or Butternut as larval host plants. Acronicta spinigera, which was previously known from only one other site in New Brunswick, was quite common at Bell Forest and at the Meduxnekeag Valley Nature Preserve (Wilson Mountain and Leonard Woods)
Less information is available on the distribution and habitat associations of Coleoptera in New Brunswick. Considering that 34 species of Coleoptera new to New Brunswick were recorded only from rich Appalachian hardwood forests during this study, it is likely that many of these may be endemic to this habitat. Because its only known larval host plant is Basswood, Saperda vestita is likely endemic to rich hardwood forests.
