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

Summer of Neotibicen tibicen tibicen – July 27th

Filed under: Neotibicen | Nymphs | Photos & Illustrations — Dan @ 5:39 pm

It can be difficult to tell which species of Neotibicen cicada is lurking inside the skin of a nymph. It you look close the hint of blue above the wing bud and green of the legs gives it away… this one turned out to be a Neotibicen tibicen tibicen

Neotibicen lyricen nymph crawling up a tree

Filed under: Neotibicen | Nymphs | Video — Tags: — Dan @ 7:43 pm

Here’s a video of a Neotibicen lyricen nymph crawling up the trunk of a fir tree, looking for a place to molt. Note the dark eyes and green wing buds. This particular pine tree is my go-to for Lyric cicadas. Here’s another: Neotibicen lyricen molting.

Monday I was doing some landscaping and I found these Magicicada nymphs feeding on the roots of a boxwood shrub. They appear to be third-instar Brood II Magicicada nymphs. 9 years old!

Periodical cicada nymphs emerging at night

Filed under: Brood XIII | Magicicada | Molting | Nymphs | Periodical — Tags: — Dan @ 5:29 am

One of the most fun periodical cicada experiences is watching thousands of nymphs emerge from the ground at night, crawl to the nearest vertical surface (hopefully a tree) and begin to molt.

This is a video by Roy Troutman from 2007 of the Brood XIII emergence, specifically in Ryerson Woods in Illinois:

Here’s a time-lapse video, also by Roy, of a cicada nymph molting:

Magicicada nymphs found by Elias, part 2

Filed under: Elias Bonaros | Magicicada | Nymphs | Periodical — Dan @ 6:02 am

Continuing from part 1, Elias Bonaros did some digging and took these photos of first and second instar Magicicada periodical cicadas on a warm winter day (March 21, 2010).

Now you know what cicadas look like when they’re underground!

Generally speaking the ones with the bulbous abdomens are second instar, and the smaller ones with the less bulbous or not bulbous abdomens are first instar.

Have you every wondered what cicadas look like when they’re underground? Elias Bonaros did some digging and took these photos of first and second instar Magicicada periodical cicadas on a warm winter day (March 21, 2010). Magicicadas have 5 instars, or phases of development. Each phase has a slightly different appearance.

This is a probable second instar nymph of Magicicada septendecim (Periodical cicada) from the 2008 Brood XIV emergence. Dug up from beneath an oak tree. It was living approximately 4-6 inches from the ground surface. Temperature 70 degrees.
