Subspecies

Six subspecies are currently recognized: * ''Araneus angulatus afolius'' (Franganillo, 1909) — Portugal * ''Araneus angulatus atricolor'' Simon, 1929 — France * ''Araneus angulatus levifolius'' (Franganillo, 1909) — Portugal * ''Araneus angulatus niger'' (Franganillo, 1918) — Spain * ''Araneus angulatus nitidifolius'' (Franganillo, 1909) — Portugal * ''Araneus angulatus personatus'' Simon, 1929 Much of the previous subspecies are now part of '' Araneus pallidus''.


Ecology

''A. angulatus'' constructs a large orb web, suspended from bushes and trees, often with support lines leading to the ground. Unlike ''A. diadematus'', the web of ''A. angulatus'' has no retreat, so the spider must sit in the centre of the web while it waits for prey. It detects prey items by vibrations they cause in the web, but has also been observed during a country
