Summary

A Total of 48 species and 160 individuals recorded

Only 5 of the species recorded in this June meeting were also recorded in May.

The cabin is surrounded by different types of broadleaf and coniferous woodland. More here
It  would be logical to assume that trees would be the main foodplants of the moths trapped in the vicinity of the cabin. However, 42% of the moths trapped had caterpillars which feed solely on herbaceous plants and grasses, 27% on broadleaved trees and only 4% on coniferous trees.

This illustrates the importance of the wildflower and grassy areas around the cabin. The fact that so few of the moth species feed exclusively on the conifers is a reflection of the fact that all of the conifers in the immediate vicinity of the cabin are imported, non-native species.
