Brittle Bladderfern

The Brittle Bladderfern (Cystopteris tenuis) is a species in the genus Cystopteris. Typically found in moist, shaded forest floors and tropical canopies.

Common Dart

<em>Andronymus neander</em>, the common dart, is a butterfly in the family Hesperiidae, commonly known as the skippers. This species inhabits terrestrial and freshwater environments, though its precise geographic range is not well documented in current biodiversity records. <em>Andronymus neander</em> typically occupies open woodland edges, grasslands, and savanna habitats, environments characteristic of many hesperiid butterflies in sub-Saharan Africa. Adults are generally fast-flying and often observed basking on low vegetation or visiting flowers for nectar. Like other members of the Hesperiidae, larvae of this species likely feed on grasses or related monocotyledonous plants, though host plant specifics for <em>Andronymus neander</em> are not extensively documented. The species is assessed as Least Concern, reflecting an absence of major threats to its populations at present. Biological traits beyond those noted here remain poorly documented in the scientific literature, and further research on this species' ecology and life history would be beneficial.
