Finding cicada nymphs in the flower garden

Filed under: Nymphs — Dan @ 4:50 pm

Today I was digging in a flower garden that is mostly inhabited by thick-stemmed Montauk Daisies, and I found many cicada nymphs. The nearest tree is about 25 feet away — I guess any type of root will suffice for some cicadas.

They seem weak and disorientated, which makes sense since they’ve lived underground their whole lives.

There are Magicicada (Brood II), Neotibicen tibicen, Neotibicen lyricen, and Neotibicen linnei in the yard. I haven’t investigated which species these are yet, but I think it’s likely they’re not Magicicada because they were relatively large (bigger than a penny) and Brood II is 6 years away.

How to tell if a Magicicada periodical cicada nymph is ready to molt

Filed under: Magicicada | Nymphs | Periodical — Dan @ 7:12 pm

How can you tell if a Magicicada periodical cicada nymph is ready to molt?

Answer: look for two black spots on its back (technically the cephalothorax). They look like they are wearing aviator sunglasses pushed up on their forehead!

A diagram that shows when a nymph is ready to molt.

I do not know the official name for these spots, but they seem to be related to the pigment that turns the cicadas black after they molt. They may scare away predators that think the spots are big eyes!

Here are a few ideas for a name for them:
obscuras maculas
mutatione macularum

Pink teneral Neotibicen lyricen

Filed under: Neotibicen | Photos & Illustrations | Teneral — Tags: — Dan @ 9:10 pm

Neotibicen cicadas come in a variety of pastel colors when they are in their teneral (soft) phase, when they inflate their wings and harden their bodies after molting their nymphal skins. Teneral Neotibicen can feature the colors pink, yellow and blue, in addition to pastel versions of the oranges, browns and greens we commonly see on their fully-hardened adult bodies.

Here’s an example of a male Neotibicen lyricen that was pink when it was teneral:

Here’s photos of the same cicada as a nymph and a hardened adult. See that its mesonotum are black and brown, not green and brown. It’s closer to a Neotibicen lyricen engelhardti than the Neotibicen lyricen lyricen, which has green on its mesonotum (the cicada’s shield-like back).

Megatibicen grossus odds and ends

Filed under: Exuvia | Megatibicen | Photos & Illustrations — Tags: , — Dan @ 7:44 pm

I had virtually no time in the summer of 2023 to look for cicadas outside my town. Also in 2023, the name of Megatibicen auletes (Germar, 1834) aka Northern Dusk Singing Cicada changed to Megatibicen grossus. While I was not lucky enough to see a Megatibicen grossus, I did find exuvia (molted skins), a headless corpse and some exit holes in late August in the Brendan Byrne park in New Jersey. Something is better than nothing.

My family and I captured and molted over 50 Neotibicen cicadas in 2023. We molt them in butterfly pavilions and then release them the next day. Most are Neotibicen tibicen tibicen (Morning cicadas).

Here’s the collection of exuvia (skins) as of August 4th.
