Chroococcus cohaerens is a species of cyanobacteria in the family Chroococcaceae, documented from freshwater and aquatic environments. Chroococcus is a genus of small, spherical to hemispherical cyanobacterial cells that typically occur in pairs or small groups of two to four cells, surrounded by individual sheaths that are embedded within a common gelatinous matrix. The cells are dark olive-green to blue-green in color due to the presence of phycocyanin and chlorophyll a pigments. Cyanobacteria of the genus Chroococcus are common components of the periphyton and plankton of nutrient-moderate freshwater bodies in temperate regions. They are found attached to submerged substrates or floating in the water column. Chroococcus species have been documented from a wide range of geographic regions including Scandinavia, where many of the described species in this genus were originally characterized. The species has no significant economic importance and is not considered a bloom-forming taxon. Its conservation status has not been assessed by the IUCN, consistent with the general approach to prokaryotic microorganisms in conservation frameworks.

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.
