It also helps to have a colorful leaf in the background, though I also like black. Dara uses focus stacking with flash for most of his shots, though this one was a single shot at f/22.

I learned a lot from insect photographer Dara Ojo, who joined our recent trip to Costa Rica and helped me take this picture of Copaxa decrescens. Olympus OM-1 / 90mm macro / iso 200. #omsystem #macrophotography #moth

A few of his tips I found most useful: shoot the face of an insect from below, looking up at it. The back is what you need for ID, but the face is where the personality is. Pick moths up off the moth sheet with a leaf - they look much nicer on a leaf than on the sheet.

I brought a 50 watt ultraviolet light (395 nanometers) to Costa Rica and it attracted a lot of cool stuff to the projector screen I am using as a moth sheet.

A cool little Mycena that I photographed in Oxapampa, Perú. Never seen one with this cool stem texture before, no idea which species it could be. Olympus OM-1 / 90 mm macro lens / 180 images stacked, ISO 200, f/5.

A cool leafhopper I photographed a couple days ago in Perú. Anyone know what species or genus it is? Reminds me a bit of Molomea but leafhoppers are really diverse.

Ceratiomyxa sphaerosperma from Mera, Pastaza, Ecuador. This tiny slime mold makes its spores on little stalks, giving it a distinctive appearance. My favorite feature of these are the glass-like stems. Olympus OM-1 / 90mm macro lens / MC20 2x teleconverter

Ps. hoogshagenii var. hoogshagenii from Mera, Ecuador. This species is in sect. Mexicanae, though it's on a long branch, so it's not super closely related to anything else. Grows in landslides and disturbed areas. I don't think anyone has cultivated it. #mycology

In 2025 I made 3000 iNaturalist observations and found 1582 species, 682 of them I had never seen before. I made 46,000 identifications for other people. I did a 5 month road trip to the southwest and east coast, went to Ecuador twice and Costa Rica once.
