🪲 Scarabaeidae. ecosystem engineers! Process tons of dung annually, recycling nutrients, reduce methane emissions, control livestock parasites & improve water infiltration.
Without them? - nutrient cycling, + flies & disease vectors, degraded pastures. Keystone species, healthy grassland worldwide.

Family Sarcophagidae (Diptera): ovoviviparous flesh flies with gray-black thoracic stripes and a checkerboard abdomen, whose larvae develop in carrion, decaying matter or as arthropod parasitoids—key decomposers in ecosystems. 🧪

The Atlantic semi-deciduous rainforest or "seasonal semideciduous forest," typically occurs as the riparian zone along riverbanks within the Cerrado biome. These forests form transitional ecotones between the open savanna vegetation of the Cerrado and the denser, humid Atlantic Forest proper🧪

Zygentoma Compound eyes, rhabdomeric photoreceptors (microvillar rhabdoms) for light detection (typical arthropod photoreceptor type)
No ocelli
Rely more on antennae/cerci than vision
Lepismatidae (silverfish) - small functional compound eyes
Nicoletiidae (soil/cave) - eyes greatly reduced/ absent

The Cerrado accounts for approximately 5% of the world's species, making it the most biodiverse savanna on Earth.
Between 1998-2008 alone, 347 new vertebrate species were described in the Cerrado (222 fish, 40 amphibians, 57 reptiles, 27 mammals, 1 bird).

Hylidae (Tree Frogs, Leaf Frogs, or Rain Frogs) is a family of anurans, whose species are found on all continents except Antarctica.
Most species inhabit trees. Some exceptions:
Lagoon-dwellers: Pseudis species live in stagnant water bodies.
Genus Scinax species thrive in urbanized environments.🧪
