We admit we got a little overexcited yesterday when we got a tip misidentifying a bug pressed against a Lower Manhattan window as a cicada. It was not a cicada. We regret the error. But today is a new day, and with it, a new cicada photo!

This one is from Midwood resident Donald Loggins, who said he snapped the above shot on his Litchi tomato plant earlier this week. "But those are not Litchi tomato leaves, they're white oak leaves" you say, because you are argumentative. That's fine. But today we're here to talk about cicadas, and that, above, is a cicada—a dog-day cicada at that, said Jody Gangloff-Kaufmann, the Community Integrated Pest Management (IPM) Coordinator at Cornell University. Compare the image above to the one below:

Dog-day cicadas actually show up once a year, usually in late summer, Gangloff-Kaufmann told us, unlike periodical cicadas, which sprout from the ground once every 13 or 17 years. (The intervals are in prime numbers to confuse mathematically-savvy predators, like birds and cicada killer wasps.) Those are the cicadas we're so eagerly anticipating now. They look like this:

Yum! While we're positively radiant at the early arrival of the dog-day cicada, we have yet to see photographic proof of the emergence of even one periodical cicada. Take a look around you. Do you suspect the creature flapping around your apartment is a periodical cicada? Look at its wings. Are they large and clear? Does it have blood red eyes and dark coloring? Congratulations, you may have a cicada! Be sure to register it here (for science) and send a photo to tips@gothamist.com (for journalism).

The bad news is that these cicadas may only be showing up on Staten Island this year. If you want to know more, the New York Entomological Society, Inc. will be discussing cicadas tonight at the American Museum of Natural History from 7 to 8:30 p.m. Click here for more information.
