Habitat & Geographic Range

Common Winter Damsel

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Luxembourg, and Sweden.

Green Sea Turtle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 8 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Australia, Brazil, Costa Rica, Indonesia, and Mexico. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Winter Damsel

<em>Sympecma fusca</em>, commonly known as the common winter damsel or common spreadwing, is a damselfly in the family Lestidae, classified as Least Concern by the IUCN. It is distributed across temperate Europe, with confirmed records from Belgium, Denmark, Luxembourg, and Sweden, and is one of the very few odonates in Europe that overwinters as an adult. This remarkable strategy distinguishes <em>Sympecma fusca</em> from most other damselflies, which overwinter in aquatic larval stages. Adults emerge in late summer, enter a reproductive diapause, and survive through autumn and winter by seeking sheltered terrestrial refugia such as dense vegetation, bark, or leaf litter. Mating and oviposition occur the following spring, typically from March onward. The species inhabits a range of standing and slow-moving freshwater habitats including ponds, marshes, ditches, and the margins of reed-fringed lakes, where larvae develop in aquatic vegetation. Like all lestid damselflies, adults hold their wings partly open at rest rather than folded over the abdomen as in most other damselflies. Biological traits including average adult lifespan, body length, and mass remain poorly documented in standardized databases, though the adult lifespan spanning overwintering can extend to several months. Ecologically, the common winter damsel contributes to freshwater invertebrate food webs as both a predatory adult and as aquatic larval prey for fish and other predators across its European range.

Green Sea Turtle

The green sea turtle is one of the largest sea turtles. They are named for the green color of their cartilage and fat, not their shells.
