Southern Dewstick Bug

Pameridea roridulae

Also known as Roridula Bug

Southern dewstick bugs spend their entire lives navigating the deadly, resin-coated foliage of Roridula plants without ever becoming entangled. They sprint effortlessly across the sticky glandular hairs to feast on entrapped insects that the plant captures. In turn, their nutrient-rich droppings provide the host plant with vital nitrogen, forming an essential mutualistic partnership in nutrient-poor fynbos soils.
