Many of us know the commonly name group of Triangular Spiders as the distinctive spiders with their distinctive triangular or heart-shaped abdomen, patterned abdomens and bright colours (often a combination of red, yellow, orange, black or white).
These brightly coloured spiders are in the genus Arkys, although this genus also include species that are well camouflaged with some species that mimic bird droppings.
