Clinton's bulrush

Clinton's Bulrush, Schoenoplectus clintoni, is a perennial wetland sedge in the family Cyperaceae with a restricted distribution in parts of the northeastern United States, named in honor of DeWitt Clinton, an early American naturalist and statesman. Like other bulrushes in the genus Schoenoplectus, it grows in shallow water and wet soils at the margins of lakes, ponds, marshes, and slow-moving streams. The stems are triangular or round in cross-section, bearing clusters of small, brownish spikelets characteristic of the genus. Bulrushes provide critical ecosystem services in wetland habitats, stabilizing shorelines, filtering water, providing nesting cover for marsh birds, and furnishing food through their seeds and starchy rhizomes for waterfowl and mammals. Clinton's Bulrush is considered rare within its limited northeastern range and faces threats from wetland drainage, development, and invasive species including common reed (Phragmites australis) that displace native emergent vegetation. Wetland loss across the northeastern United States has significantly reduced the area of suitable habitat for specialist wetland plants. The species is protected or of concern in several states where it occurs.

Common Yellow Conch

<em>Agapeta hamana</em>, the common yellow conch moth, is a small moth in the family Tortricidae. It is widely distributed across Europe and central Asia, ranging from Britain and Scandinavia eastward through much of the Palearctic region. The species inhabits dry grasslands, heathlands, chalk downlands, and scrubby habitats where its larval host plants are found. Adult moths display distinctive pale yellow to golden-yellow forewings with irregular brown or reddish-brown markings near the wingtip, forming a pattern that resembles the shell of a conch, lending the species its common name. The wingspan typically measures around 15–22 mm. Biological traits such as average adult lifespan, precise body weight, and detailed population data remain poorly documented in consolidated scientific literature. Larvae feed internally on the roots of thistles and knapweeds, particularly <em>Centaurea</em> and <em>Cirsium</em> species. Adults fly from June to August and are frequently attracted to light. <em>Agapeta hamana</em> has been investigated as a potential biological control agent for invasive knapweed species in North America, where it has been introduced experimentally. The species is assessed as Least Concern given its broad distribution and stable habitat associations.
