Common Baskettail

The common baskettail (<em>Epitheca cynosura</em>) is a dragonfly found across terrestrial and freshwater habitats of the United States. It is classified as Least Concern on the IUCN Red List, reflecting a stable and widespread population within its native range. <em>Epitheca cynosura</em> belongs to the family Corduliidae and is typically associated with ponds, lakes, marshes, and slow-moving streams, where its aquatic larvae develop. Adults are often observed patrolling over open water and forest edges in search of prey and mates. The species is named for the basket-like egg mass that females carry at the tip of their abdomen before depositing eggs in water. Males often form feeding swarms, particularly in the morning hours, where they capture small flying insects. Biological traits of this species remain poorly documented in the scientific literature.

Compact Thread-leaf Century Plant

<em>Agave microceps</em>, the compact thread-leaf century plant, is a perennial succulent in the family Asparagaceae native to Mexico, representing one of the smaller members of the ecologically and culturally significant agave genus. Agaves are iconic succulents of arid and semi-arid regions characterised by a rosette of thick, fibrous leaves typically edged with teeth and terminating in a sharp spine. <em>Agave microceps</em> typically forms compact, densely-leaved rosettes with notably narrow, thread-margined leaves, distinguishing it from larger agave species. It inhabits rocky slopes, dry grasslands, and scrublands in its native Mexican range, adapted to well-drained soils and periods of seasonal drought. Like all agaves, it is monocarpic, flowering once after many years of vegetative growth before dying, producing a tall flower spike that provides food resources for bats, hummingbirds, and insects. The species is classified as Least Concern by the IUCN, indicating a stable population without critical current threats, though many agave species face pressure from illegal collection for the horticultural trade and habitat conversion. Agaves play important roles in native ecosystems as food sources for specialist pollinators and as habitat elements on rocky hillsides. Biological traits including average lifespan in the wild, precise rosette dimensions, and population data remain poorly documented for this species compared to more commercially important agaves.
