Abstract
A canopy trap and aerial nets led to finding 8 species of Tabanidae. There was an abundance of calyptrate muscoid flies. Camel’s Hump is in the Green Mountains of western New England, USA. Discovering Diptera on Camel’s Hump involved sixteen visits over 40 years. Upwards of 23 other Diptera species are listed. Habitats on the east side and above 762 m (2500 ft) elevation on Camel’s Hump differ from the west slope but the boreal forest on both sides is influenced by cloud and fog precipitation on trees. The cliffs just above the 900 m level along the east side are often overlooked, are not seen from the summit and provide access to morning sun for insects. Recent visits explored the role of polarized skylight in relation to the canopy trap, the boreal forest environment and flies found there.
Highlights
Bell introduced a group of students to the ecology of invertebrates on Camel’s Hump (Chittenden County, 44°19'N, 72°53'W) in 1972 and I was one of them
Upwards of 15 species of calyptrate muscoid flies have been found in the large batches caught in a canopy trap
Collecting with an aerial net was the usual method of collecting flies, and most often with sweeps but for whole morning or whole afternoon sessions the canopy trap was in operation
Summary
Bell introduced a group of students to the ecology of invertebrates on Camel’s Hump (Chittenden County, 44°19'N, 72°53'W) in 1972 and I was one of them. The purpose here is to bring together results of visits in 1972 (Freeman, 1973), 1998, 1999 and 2010 with use of nets and traps. I found eight species of tabanids but few individuals. Upwards of 15 species of calyptrate muscoid flies have been found in the large batches caught in a canopy trap. Camel’s Hump (1244 m) from its summit down
