Examples of flagging from Brood X in Princeton

Filed under: Magicicada | Ovipositing | Periodical — Dan @ 10:13 pm

When Magicicada cicadas deposit eggs into a tree branch sometimes the branch dies, the leaves turn brown, and the branch droops like a flag. This is called flagging.

Here are some examples of flagging from the Brood X emergence in Princeton, NJ.

Typically flagging is more impactful to trees imported to North America, but it also impacts native species. The positive aspect is it prunes weaker branches, which helps the tree, and helps other plants in the shade of the tree.

If you want to learn whether eggs/larva survive flagging read FLAGGING: HOSTS DEFENCES VERSUS OVIPOSITION STRATEGIES IN PERIODICAL CICADAS (MAGICICADA SPP., CICADIDAE, HOMOPTERA) by JoAnn White. Hint: very few survive.

Periodical cicadas are known for their unique 17- and 13-year life cycles and mass emergence events. This mystery of why they would have evolved these two prime-numbered life cycles has attracted many biologists and mathematicians. Dr. Yoshimura will explore this phenomenon

Platypedia putnami survey at Horsetooth Mountain Open Space by Tim McNary

Filed under: Platypedia | Platypediini | Proto-periodical | Tim McNary — Tags: — Dan @ 6:12 pm

Here’s a short 2021 update for the Platypedia putnami survey at Horsetooth Mountain Open Space, west of Fort Collins, Colorado. 2021 is turning out to be a very large emergence for this cicada, and it’s not through yet! The survey transect goes from the trailhead parking lot to Horsetooth Falls. Although the first exuvia found was on May 22, 2021, the bulk of the exuvia, so far, have emerged (153 of 201 exuvia) June 5-8th. “Clicking” of adults can be heard in many areas, but is concentrated in certain sites.

Different types of Magicicada periodical cicada holes

Filed under: Brood X | Chimneys | Magicicada | Periodical — Dan @ 5:19 pm

Different types of Magicicada periodical cicada holes found in Princeton, NJ. Brood X, 2021. Generally speaking, their holes are about the size of a dime. You won’t see a spray or kickback of soil around the hole like you would when an animal is digging into the soil rather than coming out of it (cicadas are coming out).

Periodical cicada nymphs emerging at night

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

One of the most fun periodical cicada experiences is watching thousands of nymphs emerge from the ground at night, and 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:
