Bolbonota
seed-mimic treehopper
Bolbonota is a genus of treehoppers in the family Membracidae, tribe Membracini, distributed in the New World tropics and subtropics. Adults are characterized by their dark, globular body form with a corrugated pronotal surface and distinctive red eyes. The genus contains at least a dozen described species in Brazil alone, with many more likely awaiting description. Bolbonota species exhibit complex ontogenetic color changes: early instar nymphs are dark, late instars become mottled or streaked white, and adults revert to dark coloration.
Bolbonota tuberculata
Bolbonota tuberculata is a treehopper species in the family Membracidae, characterized by its globular, tuberculate body form and dark coloration. The species belongs to the New World tribe Membracini and exhibits the pronotal modifications typical of this group—an enlarged, helmet-like structure that extends over the body. Like other members of the genus Bolbonota, adults have been observed with distinctive red eyes. The species occurs in the Neotropical region, with records from French Guiana and Brazil.
Erythrodiplax
Dragonlets
Erythrodiplax is a large Neotropical genus of small to medium-sized dragonflies in the family Libellulidae, commonly known as dragonlets. The genus contains numerous species distributed across the Americas, with some members exhibiting unique ecological adaptations. Erythrodiplax berenice, the Seaside Dragonlet, is the only odonate known to develop in saline water, tolerating salinities up to 48%. Species within this genus display diverse reproductive behaviors, with males exhibiting territorial or satellite strategies and engaging in mate guarding during oviposition.
