Cleopatra

The Cleopatra, Gonepteryx cleopatra, is a large, striking butterfly in the family Pieridae found across the Mediterranean basin, including southern Europe from Portugal and Spain east to Greece and Turkey, and extending into North Africa and the Middle East. The species is closely related to the common Brimstone butterfly but is larger and more vividly colored. Males display brilliant yellow-orange upperwings with a distinctive deep orange patch on the forewing, while females are pale greenish-white, resembling the Brimstone. The undersides of both sexes are pale green, providing excellent camouflage when resting on vegetation. The Cleopatra inhabits warm, rocky hillsides, maquis, garrigue, woodland edges, and citrus groves where its larval host plants, buckthorns (Rhamnus species), are present. Adults are strong fliers, frequently visiting flowers for nectar. Like the Brimstone, the Cleopatra overwinters as an adult, sheltering in dense evergreen vegetation during the coldest months and re-emerging on warm winter days. The species produces one generation per year. It is widespread and locally common across its Mediterranean range and is assessed as Least Concern by IUCN, though habitat loss from agricultural intensification and urbanization affects local populations.

Common Water Rat

<em>Hydromys chrysogaster</em>, commonly known as the common water rat or rakali, is a semi-aquatic rodent in the family Muridae, native to Australia and New Guinea. It is classified as Least Concern by the IUCN, reflecting its relatively stable population across a broad range of freshwater and estuarine habitats on the Australian continent and associated islands. The species typically inhabits the banks of rivers, lakes, wetlands, and estuaries, where it constructs burrows in streambanks. It is highly adapted for an aquatic lifestyle, with partially webbed hind feet, a flattened head, and a dense waterproof coat. <em>Hydromys chrysogaster</em> is a carnivore, typically feeding on fish, crustaceans, mussels, frogs, and aquatic invertebrates, which it often carries to elevated feeding platforms to consume. The species is nocturnal and crepuscular, most active during early morning and evening hours near the water's edge. Biological traits including average lifespan, body length, and weight remain poorly documented in standardized databases, though adults are generally robust for a rodent, reportedly reaching body lengths of 20–35 cm excluding the tail. Geographic range details for this particular record remain incompletely documented in available data sources. Ecologically, the common water rat is an important apex predator in small-scale freshwater food webs and serves as an indicator species for wetland health in Australian riparian systems.
