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.

Here’s a video from Jin Yoshimura who researches periodical cicadas.

The Evolutionary Origin of Periodical Cicadas: A Sci-Fi Story:

The Evolutionary Origin of Periodical Cicadas: A Sci-Fi Story:
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
