This tiny insect is a male Red-headed Bush Cricket, Phyllopalpus pulchellus. He generates a very loud tinkling song for such a small animal.
I recorded this sound taking a walk at approximately 10:15 pm, Wednesday, September 18, 2013. These insect sounds were coming from a very tall, thick patch of grass near a culvert/drainage area by the sidewalk. Likely there are multiple species present in the recording.
Loud insects in the middle of the day, while walking through the trails in the Indian River Lagoon Preserve State Park.
Singing at Little Bennett Park a few feet into the forest with grassy ground cover and tree canopy. Forest margin, ~75 F.
I live in the historic Grant Park neighborhood of Atlanta. The area is covered in centuries-old trees, and this recording is of some kind of bug that enjoys hanging out in the 70-ft walnut tree in my backyard and chirping loud enough to wake me up around sunrise.
This is a pilot for what we hope will become a coordinated effort to document the distribution of calling insects using recordings as primary vouchers. The emphasis will be on collecting records at the county level, but there is no reason that multiple records at much smaller scales can't be recorded for parks, refuges, and personal projects.
