Phymateus viridipes

While not directly poisonous to the touch, Phymateus viridipes accumulates toxic defensive chemicals from the plants it consumes, making it highly unpalatable to predators. These toxins, known as cardiac glycosides, are primarily dangerous to birds and small mammals who might attempt to eat them. Handling them is generally safe for humans, but it is recommended to wash your hands thoroughly afterward.

This species of African grasshopper feeds on specific toxic plants within their native savanna habitat, particularly those from the milkweed family. By consuming these toxic plants, they absorb and store the defensive chemicals within their own bodies. This specialized diet is directly responsible for their toxicity to predators.

The bright green markings and vivid aposematic coloration of this grasshopper serve as a warning signal to potential predators. Because they accumulate unpalatable chemicals from the toxic plants they eat, they must advertise their foul taste visually. This striking appearance tells birds and lizards that eating the grasshopper will make them sick.

Phymateus viridipes is native to the savanna and bushveld regions of Southern and Eastern Africa. They are typically found in areas where their specific host plants grow abundantly. Countries like South Africa, Zimbabwe, and Mozambique are common ranges for this distinctive insect.
