Ever since I got a replacement for my old Sigma EM-140 ring flash (it's an older model and it doesn't flash on my EOS D77), I've been back to shooting macros out of doors. The cheap replacement for the Sigma ring is a "KF150 TTL Marco (Sic) Ring Flash," which seems to be doing a decent job.
iNaturalist is a citizen science project and online social network of naturalists, citizen scientists, and biologists built on the concept of mapping and sharing observations of biodiversity across the globe.
I've joined iNaturalist and have posted a number of my recent shot to the site, along with my tentative classifications. Boy, what a humbling experience. My identifications have been largely challenged by the experts, and I have little to doubt their authority as to the correct species.
I had labelled this a a Dog Day Cicada (Neotibicen canicularis):
However, it turns out that it's really a Common Swamp Cicada (Neotibicen tibicen). To my delight, this photo has been flagged as a "research grade."
One other earned that classification. I'd originally identified this as a Modest Masked Bee (Hylaeus modestus), but that has been corrected to be an Eastern Masked Bee (Hylaeus affinis). At least I've been getting the genus right.
