I was walking in a field recently, and when I took my shoes off, I happened to step on some strange insect. It stung me really hard, the stinger was sharply curved and maroon in color, as was most of the insect. It was much smaller than a honeybee, but I freaked out and flung the bug off too quickly to really examine every detail of it's appearance. I recall it having wings. The sting burned and itched like crazy for days, even after thorough cleaning. What could it have been?
