Some species maintain their wax-making glands into adulthood, but others don't. Females of many species, however, produce wax to protect their eggs.
Since they're immature, planthopper nymphs are super tiny, as seen in this comparison to a human fingertip.
This is what an adult planthopper looks like if it hangs onto its wax-making abilities. Unfortunately, planthoppers are often vectors for plant diseases.
This little beastie is a baby planthopper, that researchers recently documented during an expedition to southeast Suriname. This particular creature isn't a fresh discovery, but the Conservation International team did find 60 species they believe are new to science.
