cluster fig

Ficus racemosa, commonly called the cluster fig or red river fig, is a large deciduous to semi-evergreen tree in the family Moraceae with a native range spanning tropical Asia, including the Indian subcontinent, Southeast Asia, and extending to northern Australia. Despite records suggesting Brazil and Taiwan, the species is most reliably native to South and Southeast Asia. The cluster fig is famous for its remarkable reproductive strategy: fruits grow directly from the trunk and major branches in dense clusters, a habit known as cauliflory. These figs are critical food resources for a wide array of frugivores including bats, birds, monkeys, and civets, making F. racemosa a keystone species in riparian and moist deciduous forests. Trees can reach 15–30 meters in height and develop buttressed bases when growing along riverbanks and in seasonally flooded areas. Like all figs, Ficus racemosa shares an obligate mutualism with its specific fig wasp pollinator, without which reproduction is impossible. Fruits have long been used in traditional medicine across South Asia to treat various ailments. The tree is classified as Least Concern by the IUCN, reflecting its wide distribution and adaptability, though local populations may face pressure from deforestation and river channelization in its native range.

Coastal Silver-stiletto

Coastal silver stiletto (Acrosathe annulata) is a slender robber fly in the family Therevidae, native to northwestern Europe, including the United Kingdom, France, the Netherlands, Belgium, and Scandinavia. Adults are found on coastal sand dunes and sandy heathland, where they perch on bare sand to ambush small flying insects. Stiletto flies in the family Therevidae are characterised by a slender body, long pointed abdomen, and predatory habits; adults prey on a variety of small dipterans and other flying insects during warm, sunny periods. Larvae develop in sandy soil, where they are also predatory, feeding on other invertebrate larvae. Acrosathe annulata is a habitat specialist restricted to open, sandy coastal habitats with sparse vegetation—environments that have declined substantially across northwestern Europe due to dune stabilisation, recreational disturbance, and the cessation of traditional dune management. The IUCN lists it as Least Concern, though regional conservation bodies in the United Kingdom have flagged population declines. It is considered an indicator of high-quality coastal sand dune habitats and is monitored through national invertebrate surveys.
