Macroarthropods

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. Studies in the Brazilian Pantanal, where livestock is the main economic activity, confirm these beetles maintain dung removal and soil bioturbation.🧪

Scarabaeidae. Over 76 species across 20 genera have been documented in Brazilian pasturelands, providing biological control and parasite suppression by burying harmful insects and worms with dung.🧪

🪲 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.

Camponotus fragilis, medium-sized carpenter ant (6–8 mm) found in Atlantic Forest and humid cerrado habitats, known for nesting in hollow branches and rotting stumps. It frequents crepuscular and nocturnal foraging trails, with peak activity just after sunset. 🧪#Formicidae #Camponotus #Entomology"

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
🧪

Cool! Bookmarked and reading!

Wow! It is amazing! Thank you for sharing.

Thank you!

The transition of vegetation from the lowly water-stressed forest with high tree cover to a savanna-grassland regime with low tree cover and the utilization of rootzone storage capacity to cope with the spatial change to a drier climate.

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 🧪

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).

Mammals: ~199-200 spp
Birds: ~ 837-860 spp
Reptiles: ~120-180 spp
Amphibians: ~150-200 spp
Fish: ~800-1,200 spp
Insects: ~90,000 spp
Endemic Species:
Mammals: 11
Birds: 30
Amphibians: 72
Fish: ~200

Brazil's CERRADO: 2M km² savannah with 12,000+ plant species (45% endemic). Called "upside-down forest" - roots reach 20m deep, storing 60% of biomass underground. Fire-adapted biodiversity hotspot. 50% destroyed, only 3% protected. One of Earth's most threatened ecosystems. Science🧪

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. 🧪

Brazilian Atlantic Forest harbors 23 Neoponera ant species! These remarkable predators serve as forest health indicators while producing antimicrobial venom compounds with potential medical applications. New species still being discovered in this biodiversity hotspot. 🧪

I can think of at least one hypothesis. This could involve Batesian mimicry, since Euglosini bees have stings that can be used as a defence against predators. The sting of a female Euglosini is less painful than that of a honey bee and, unlike honey bees, these bees can sting repeatedly.

Ornidia flies don’t just look like orchid bees—they ACT like them, mimicking bee behavior with similar wing buzz and leg movements! Worldwide, synanthropic. "Green Jewel Flies" help in determining time of death through predictable patterns on decomposing matter. #Evolution #ForensicScience
