Menemerus bivittatus, the Gray Wall Jumping Spider. Small sized incredible hunter with amazing eyesight. It doesn't build webs but is a master of the precision pounce.
✅can take down prey twice their size!
✅Native to Africa, they're now a cosmopolitan citizen, found from the Americas to Asia.🧪

For macro photography, capturing a 2.1x magnification photo of a fly’s head then cropping provides better fine resolution and depth of field than zooming in optically at 4.1x or 5.1x. This approach balances sharpness and focus control without shallower depth of field of higher magnifications.

🪰 Eicherax is a genus of robber flies (Diptera: Asilidae) found in the Neotropical region. It belongs to the subfamily Asilinae and represents one of the 11 generic groups within this subfamily. These predatory flies hunt other arthropods throughout Central and South America.🧪

🪲 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.

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

Silvery-white covering are flattened, overlapping scales; give Zygentoma metallic appearance. Scales modified setae; provide protection, reduce water loss
Prominent bristles on head and body; sensory functions, detecting air movement and vibrations
Particularly concentrated around sensory organs 🧪

ZYGENTOMA: The living fossils of the insect world!
Known as silverfish, these apterygote insects (wingless) have existed for over 400 million years virtually unchanged. They're detritivores that feed on carbohydrates like cellulose and starch. 🧪
