Brownfish

The Brownfish (Actinopyga echinites) is a species in the genus Actinopyga. It is currently classified as Vulnerable on the IUCN Red List. Native to Asia, inhabiting ecosystems characteristic of the region.

Common Lacehopper

The Common Lacehopper (<em>Cixius nervosus</em>) is a planthopper insect in the family Cixiidae, classified as Least Concern on the IUCN Red List. It is native to Europe, with records from five European countries, and also occurs in the United States in North America. The species typically inhabits virtually all terrestrial and freshwater habitats within its range, demonstrating broad ecological tolerance. Lacehoppers are hemipteran insects that feed on plant sap and are often associated with roots or low-growing vegetation. Adults typically emerge in summer and are capable of short flights between host plants. The Common Lacehopper's widespread distribution and occurrence across a variety of natural and semi-natural habitats support its stable conservation status. Its role in food webs as a prey item for insectivorous birds and other invertebrate predators gives it ecological significance within temperate ecosystems. Biological traits of this species remain poorly documented in the scientific literature.
