Araneus marmoreus, commonly known as the marbled orb-weaver, is a colorful spider found in temperate forests. It is notable for its vibrant, marbled abdomen and impressive web-building skills. This species is often seen in wooded areas, gardens, and near bodies of water, playing a crucial role in controlling insect populations.

Araneus marmoreus, commonly known as the Marbled Orb-weaver, is native to the Holarctic region. This species is found across North America, Europe, and parts of Asia, including countries such as the United States, Canada, most of Europe, and extending into Russia and Japan. Its geographical distribution encompasses temperate regions where conditions are suitable for its survival and reproduction.

The Marbled Orb-weaver typically inhabits forested areas, gardens, and meadows. It prefers environments that provide ample vegetation for web construction, such as deciduous and mixed forests. The climate in its habitat is generally temperate, with variations in temperature and humidity that support diverse insect populations, which are crucial for its diet.

Araneus marmoreus occupies the niche of an arboreal and terrestrial predator. It constructs large, spiral orb webs to capture flying insects, which it primarily feeds on. The species is adapted to live in areas with dense foliage, which aids in web attachment and camouflage. It plays a significant role in controlling insect populations within its ecosystem.
