New iNaturalist Project: Magicicada Flagging Project

Filed under: Flagging | Magicicada — Dan @ 3:46 pm

I created a new iNaturalist project called the Magicicada Flagging Project to track tree flagging damage by Magicicada cicadas.

Upload a tree or branch with flagging to iNaturalist, add it to the Magicicada Flagging Project, and when it asks you if the observation has “Magicicada Flagging” select “yes”.

Magicicada Flagging Project

When Magicicada cicadas lay eggs in the branches of trees (ovipositing) branches may become damaged or die which causes the leaves to turn brown. This is called flagging. Magicicadas, depending on their location, oviposit between late April through to the end of June. Flagging will appear in the weeks following ovipositing. Leaves will remain brown throughout the year.

The project leverages the observation field Magicicada Flagging set to yes.
Observation Field

The project works regardless of whether the organism is identified as a type of tree (oak, chestnut, etc.) or a Magicicada cicada. Most people identify trees with flagging as a “Magicicada” but I would not want to take away the option to allow people to identify a tree (oak, chestnut, etc.) over the type of cicada that did the damage.

There is a similar observation field for cicada presence set to flagging/oviposition scars, but it’s not specific to Magicicada and oviposition scars do not always accompany flagging. I do encourage you to use this observation field as well!

A short Neotibicen season in New Jersey. Male teneral Neotibicen tibicen.

Filed under: Molting | Neotibicen — Tags: — Dan @ 7:30 pm

We had a short Neotibicen cicada season in New Jersey in 2022.

I’m used to finding molting Neotibicen cicadas between the first week of July and the last week of August. This year they started emerging in the first week of July, but the last one I found was on August 2nd.

I wonder if the short season was due to the major drought or heat waves New Jersey experienced this summer.

Here are some photos of a freshly-molted/teneral(soft) Morning cicada:

Examples of flagging from Brood X in Princeton

Filed under: Flagging | 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.
