Zombie Cicadas??!

M. septendecim missing the body

Magicicada cicadas are often the victims of bird attacks or fungus infestation, which results in the removal of the cicada’s abdomen. Sometimes a bird removes the cicadas head. In both cases, the cicada’s body keeps moving, and some people question whether or not the cicada then becomes a zombie. No, the cicada does not become a zombie.

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.
