Your letter to the bugman:  This giant was just happily sitting on the wall outside of my son’s daycare.
He was HUGE! At least 2 inches tall. What was it?

Dog Day Harvestfly

Dear JS,
Though it is commonly called a Dog Day Harvestfly because of its end of summer flight time and because it resembles a giant fly, the Annual Cicada is not a true fly.  Cicadas are also well known because of the cacophony they produce from tree tops.

Lovely! Thank you Daniel! 🙂

Ed. Note:  There has been some chatter on Facebook accusing us of making up the common name Dog Day Harvestfly.  According to BugGuide, of the genus Neotibicen:  The name ‘Dog Day Cicada’ is most often applied in particular to Neotibicen (Tibicen) canicularis. Other common names encountered:  Harvestflies, Dryflies, Jarflies.”  BugGuide also note on the page for :  “Other Common Names Dogday Harvestfly, Harvestfly, Northern Dog-Day Cicada, & Common Dog-Day Cicada” with the explanation “DOG-DAY: a reference to the hot ‘dog days’ of late summer when this species is heard singing; at this time in the northern hemisphere the Dog Star (Sirius) is above the horizon in the Big Dog constellation (Canis Major).  NOTE: Dog-days of summer indeed do refer to Sirius, the dog star, and although it is above the horizon, it is not visible in summer in the northern hemisphere. This is because it is up during the daytime. Canis major is a “winter” constellation. Canis Major CANICULARIS: from the Latin ‘canicula’ (a little dog, the Dog Star, Sirius) HARVESTFLY: another reference to the late season song of this species, heard during harvest time.”
