在秘鲁的摩奴河附近，一条身上长着刷子似的吸管的刺毛虫正盘踞在一片叶子上。这种肥嘟嘟的毛虫身上颜色艳丽的毛发，或称为吸管中含有轻度毒性的毒素，以此御敌。然而，仅仅碰触这种刺毛虫就会引起毒素的传递，将导致红疹，肿胀，在某些情况下还会出现发烧和恶心等症状。

The stinging hairs, or suckers, of these brightly colored, fleshy caterpillars contain mildly venomous toxins used for defense purposes. However, simply touching a slug caterpillar triggers toxin transfer, which causes rashes, swelling, and in some cases, fever and nausea.
