Red spiderling enjoys a broad geographical presence, spanning continents such as Asia, Africa, North and South Americas, and Oceania. While native to regions including the Caribbean, Middle East, and parts of Asia, red spiderling has been introduced to a diverse array of territories in Asia and Africa, as well as countries in South America. In certain areas, red spiderling is sometimes thought to be invasive, potentially influencing local ecosystems, notably in parts of South America and East Asia.
