What kind of bug is this?

I found this bug by our back door. It's not made any sound except for flittering, so I don't think it's a cricket or a cicada. Our door was open last night but I didn't hear it until today, not sure if it's nocturnal or diurnal.

Curator Response

Hi Caitlin,

This is a cicada in the genus Platypedia, sometime referred to as “wing-tapping cicadas.” These cicadas are the earliest to emerge in the Santa Barbara area, with adults active as early as February! Unlike many cicadas that produce loud, harsh buzzing calls, the song of Platypedia is a softer clicking noise. Like other cicadas though, it is only the males that regularly sing, so it is quite possible that yours is a female. Platypedia are generally diurnal, but may occasionally be attracted to lights at night, which is likely how it ended up at your back door.

Sincerely,

Schlinger Chair of Entomology Alex Harman, Ph.D.
