ciliate oak scale

Ciliate oak scale (Eulecanium ciliatum) is a soft scale insect in the family Coccidae, found in Europe. Like other soft scales, the adult female forms a protective waxy or leathery scale cover under which she lays eggs and overwinters. Eulecanium ciliatum is associated with oak (Quercus) as its primary host, though it may also occur on other deciduous trees. The species feeds by piercing plant tissue and extracting phloem sap, and heavy infestations can weaken host branches; however, it is generally not considered a major economic pest. The name ciliatum refers to fringed or ciliate margins of the scale cover or body. Scale insects of the family Coccidae are widespread in temperate and subtropical regions, and many European species are incompletely documented in terms of distribution and population status. Eulecanium ciliatum has not been formally assessed by the IUCN. Natural enemies including parasitoid wasps, predatory beetles, and lacewings help regulate scale insect populations in forest ecosystems. The taxonomy of European Eulecanium has been subject to revision, and several historical records may require reassessment given updated species concepts. Oak forests across Europe support a rich community of specialist scale insects, many of which provide food for insectivorous birds during the nesting season. Conservation of mature oak woodland benefits the entire community of oak-associated invertebrates.

Comoro Rousette

<em>Rousettus obliviosus</em>, the Comoro rousette, is a fruit bat in the family Pteropodidae endemic to the Comoros archipelago in the Indian Ocean, primarily recorded from Anjouan and Mohéli islands. As an Old World fruit bat, it plays an important ecological role in pollination and seed dispersal across the island's native forests. The species inhabits tropical moist lowland and montane forests, roosting in caves and dense vegetation. Its range is severely restricted by the small land area of the Comoros, making it inherently vulnerable to habitat loss. Deforestation driven by agricultural expansion and charcoal production has significantly reduced available forest cover on the islands. The IUCN classifies the Comoro rousette as Vulnerable, reflecting ongoing population pressures and limited geographic distribution. It is presumed to feed on fruits, nectar, and pollen typical of Old World fruit bats, though detailed dietary studies are limited. Biological traits including precise body measurements and lifespan data remain poorly documented in the scientific literature. Conservation efforts on the Comoros islands face challenges due to limited resources, though the species benefits from some protection within national parks and forest reserves. Its survival depends on the preservation of intact native forest habitat across the archipelago.
