Winthemia primarily target Lepidoptera; varying levels of host specificity. Parasitism across multiple lepidopteran families: - Noctuidae (armyworms, cutworms), Saturniidae (giant silkworm moths), Tortricidae (spruce budworm), Nymphalidae (brush-footed butterflies), Geometridae (measuring worms)

🪰Winthemia "pinguis"? parasitic tachinid fly targeting Lepidoptera larvae. Native to North America, adults feature hairy eyes, short proboscis for honeydew feeding, and oval abdomens. If I have correctly identified the species, this is an invasive species in Brazil. Micro 4 /3 camera set. Science🧪

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.

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🧪

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).

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.
