Medium-wing Kitespider

Gasteracantha milvoides is known from Central African Republic, Kenya, Namibia, Zimbabwe, Eswatini and South Africa. The South African distribution includes Eastern Cape, KwaZulu-Natal, Limpopo, and Mpumalanga provinces, where the species occurs in numerous protected areas including Hluhluwe Nature Reserve, iSimangaliso Wetland Parks, Ndumo Game Reserve, Kruger National Park, and Lekgalameetse Nature Reserve.

Gasteracantha milvoides is an orb-web dweller commonly found in warmer tropical regions. The orb-webs are usually constructed in trees or tall shrubs, from waist height to above the observer's eye level. The bridge line is frequently longer than the orb part, giving the impression that the spider is floating in space. The web is sometimes decorated with tufts of silk. The spiders are active during the day and do not remove their webs. The species has been sampled from the Forest, Indian Ocean Coastal Belt, Grassland, Savanna and Thicket biomes at altitudes from 5 to 1,341 m above sea level.
