Ciliolate Aster

Ciliolate aster (Symphyotrichum ciliolatum) is a perennial wildflower in the family Asteraceae, native to central and northern North America, from the Great Plains east through the Great Lakes region and into the northeastern United States and southern Canada. It grows in open woodland, prairie margins, roadsides, and disturbed ground, preferring well-drained to moderately moist soils with full sun. The plant produces upright stems 40–100 centimeters tall bearing alternate, clasping leaves with slightly fringed (ciliolate) margins, and branched clusters of lavender to blue-violet daisy-like flower heads with yellow disc florets. Blooming occurs in late summer and autumn, providing important nectar for migrating monarch butterflies and native bees. Symphyotrichum ciliolatum is classified as Not Evaluated by the IUCN and is common across its native range. The genus Symphyotrichum was split from the broadly defined Aster following molecular phylogenetic work that demonstrated the non-monophyly of the traditional genus. Ciliolate aster is one of many native North American aster species with a wide distribution, though it is absent from Europe despite some database records listing Norway as its country—an artifact of data entry errors in global species databases. Conservation of native prairie and open woodland habitats benefits this species alongside its many pollinators.

Common Big-eared Bat

The common big-eared bat (<em>Micronycteris microtis</em>) is a small insectivorous bat belonging to the family Phyllostomidae, native to tropical and subtropical regions of South America. Its range includes Colombia and Venezuela, where it typically inhabits diverse terrestrial and aquatic environments including forests and riparian zones. It is classified as Least Concern on the IUCN Red List, indicating a relatively stable population. As its common name suggests, <em>Micronycteris microtis</em> is distinguished by notably large ears relative to its body size, which enhance its echolocation capabilities for detecting prey and navigating complex forest environments. The species is often associated with lowland and foothill forests, roosting in caves, hollow trees, and dense vegetation. It typically feeds on insects and may also consume small vertebrates or fruit on occasion. Biological traits of this species remain poorly documented in the scientific literature.
