Cluster Bat

Myotis sodalis, the Indiana bat or cluster bat, is a medium-sized insectivorous bat in the family Vespertilionidae endemic to the eastern United States. It is one of the most endangered bats in North America, listed as Endangered under the U.S. Endangered Species Act and classified as Near Threatened by the IUCN. The species is named for its behavior of clustering in extremely dense hibernation groups—sometimes thousands of bats per square meter—in specific limestone caves and mines during winter. These few critical hibernacula make the species extremely vulnerable to disturbance and disease. Since 2007, Indiana bats have suffered severe mortality from white-nose syndrome, a fungal disease caused by Pseudogymnoascus destructans that disrupts hibernation and causes mass starvation. During summer, Indiana bats roost under loose bark of dead trees and forage for insects over forested landscapes and riparian areas. Foraging individuals consume moths, beetles, and flying insects. Conservation efforts include cave gate protection, white-nose syndrome research, and summer habitat management on public and private lands across the eastern US.

Common Fieldcap

The Common Fieldcap (<em>Agrocybe pediades</em>) is a saprotrophic fungus belonging to the genus Agrocybe within the family Strophariaceae. It typically produces small, tan to pale brown cap-shaped fruiting bodies and is often found growing in clusters or scattered on lawns, grassy areas, forest floors, decomposing wood, and soil-rich ecosystems. The species typically inhabits forest floors, decomposing wood, and soil ecosystems, obtaining nutrients by breaking down dead organic matter. Its geographic range includes several European countries — Belgium, Denmark, Norway, Portugal, and Sweden — as well as the United States in North America. <em>Agrocybe pediades</em> is assessed as Least Concern on the IUCN Red List, reflecting its broad distribution and apparent stability. Biological traits of this species, including specific data on fruiting body size, lifespan, and ecological preferences, remain poorly documented in the scientific literature. Like other members of its genus, it typically fruits during warmer months and often appears after rainfall in nutrient-rich grassland and woodland habitats.
