Female Tabanus Horse Fly
I haven't been going out looking for bugs as much as I would like to as it has been quite hot around here lately (over 100 degrees). But I did manage to take a short drive out to Lake Bixhoma this afternoon with the usual hopes of finding new jumping spiders. Although I only found one common salticid, I had a great afternoon. After just an hour or so, my eyes were filling with sweat so fast, looking through the viewfinder was nearly impossible. I decided to call it a day at that point, as I ruined a few buttons on my last camera from sweating. What happens is that when I look through the viewfinder, the tip of my nose rests right on the playback button, and effectively acts like a funnel channeling all my sweat right into the button.
This female horsefly was circling and buzzing around me for a good half an hour before I came across an overgrown concrete picnic area. She immediately flew underneath a broken concrete table and rested on the underside. I caught her in a toothpick container and headed home as I didn't feel like attempting to photograph her there. Once home, I smeared a bit of honey on a stone outside and let her loose. She went right for the honey, I took a few photos, and then she flew away (all within about 30 seconds).
The photo was taken with the 50mm reversed on a few extension tubes.
