Visualizing all periodical cicada broods

Isn’t this a lovely picture (updated with colors sorted)?

All Broods

This image represents the combined range of all Magicicada periodical cicada broods, including the extinct Broods XI (last recorded in Connecticut) and XXI (last recorded in Florida).

To produce this image, I visited John Cooley’s Cicadas @ UCONN (formerly Magicicada.org) Cicada Geospacial Data Clearinghouse and downloaded the Shapefile of Magicicada broods. Then I used the computer program QGIS to change the Shapefile to a KML file, and then I opened the file in Google Earth. Credit goes to John for pulling the data together into the Shapefile.

I manually edited the KML file to try to give each Brood a different color.

An interesting area is Fredrick County, where 5 different broods seem to exist (or have existed) at once.
Fredrick County VA

Peach = Brood I
Green = Brood II
Purple = Brood V
Cyan = Brood X
Red = Brood XIV

It’s also interesting that four of the broods are separated by four years: X, XIV, I, V.

Green Grocer

I felt bad about always using an illustration of North American cicadas, so I made a Green Grocer cicada for Australian fans.

Get this image on a shirt, mug or even a pillow case via CafePress (the mugs are the most affordable).

The excavation skills of cicadas

Filed under: Anatomy | Magicicada | Roy Troutman — Dan @ 8:01 am

Cicadas spend most of their lives, as nymphs, underground. The large forelegs of cicada nymphs are adapted to digging through soil.
