Cicadas are supposed to look like this, complete with no holes and perfect eyes.
However, this past August, I found this poor Cicada (which is not a dog day cicada [Tibicen canicularis] as pictured above, it is perhaps a swamp cicada [Tibicen tibicen], but I'm not positive), whose eyes had been picked out and its thorax had a large, cavernous hole revealing the inside pinkish flesh. What could be more gross than a mortally wounded insect? This guy was still living when I snapped these images, a testament to the survivability of these creatures.
Our yard was loaded with dog day cicadas this year, but I only observed this one swamp cicada. I'm sure Cicada larva feast on the roots of our stately bur oak, and I'm glad that they do. While some may consider them gross, cicadas are great insects to photograph. One, they are big, so you get very nice images even without a dedicated macro lens, and second, they are slow and not apt to fly away once you've captured one. Fore more cicada images, check out Cicada Mania, a site I originally learned about after my first cicada post this summer, to which Cicada Mania linked.
