Will Brood XIV cicadas appear in the DMV? Yes, no, and maybe – Magicicada septendecim, Magicicada cassini and Magicicada septendecula

 

Will cicadaphiles in the DMV have a chance to see beautiful periodical cicadas near their homes this year? Yes, no, and maybe.

 

During the past two months, Bug of the Week’s peregrinations took us to the tropical rainforests of Belize to visit stingless bees, sassy assassin bugs, red rump tarantulas, headlamp beetles, incredibly fast whip spiders, fungus-loving leafcutter ants, and rapacious army ants. This week we hop-scotch fifteen hundred miles north to the DMV to check on the progress of Brood XIV (14) periodical cicadas. Last week journalists proclaimed the upcoming arrival of millions (or is it billions?) of cicadas set to emerge in a dozen eastern states. The appearance of periodical cicadas in the DMV this year looks like a definite yes, no, and maybe. According to the Cicada Mania website, a source of all things cicada, Virginia is a definite yes. Brood XIV is a brood of all three species of 17 - year cicadas, Magicicada septendecim, Magicicada cassini and Magicicada septendecula, that was last seen in 2008 in Botetourt, Lee, Russell, Scott, Smyth, Tazewell, and Wise counties. Unfortunately, the District of Columbia appears to be a definite no. While historical maps by Charles Marlatt and Roy Troutman appear to show Brood XIV in D.C., more recent compilations indicate that this is not the case.

Seventeen years ago, back in 2008, eggs of periodical cicadas hatched. After stretching their legs a bit, tiny nymphs dropped form tree branches down to the earth below. They entered the soil sometimes using the very holes from which their parents emerged but few weeks earlier. After sucking sap from plant roots for a few years, they grew to the size of a jelly bean. But just three years ago, they were almost an inch in length. In locations where they will emerge you can visit Brood XIV cicadas by carefully turning the soil with a shovel. After your visit, please return them to the soil and gently cover them with earth so they will emerge with the rest of their brood mates later in spring.

The maybe part comes with Maryland. Until very recently Maryland was listed in some sources as a state that would host Brood XIV cicadas in Washington and Allegheny Counties. There are several historical accounts of Brood XIV cicadas emerging in these counties dating back to the 1900s and 1940s. In 2008 along the Potomac River near Hancock, Maryland a localized ensemble of periodical cicadas was observed. Whether these were Brood XIV cicadas or not remains a mystery. Cicada researchers suggest that these may be stragglers from Brood X, time travelers that emerged four years behind the massive emergence of their brood-mates in 2021. This Bug Guy hopes that periodical cicadas are hanging on in Washington and Allegheny Counties. He plans to spend a lot of time wandering the C & O canal this spring and summer to catch a glimpse of Brood XIV or maybe the stragglers of Brood X. 

So, if you are concerned that periodical cicadas may not show this spring, put your fears to rest. In addition to Virginia, periodical cicadas will appear in parts of Georgia, Indiana, Kentucky, Massachusetts, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, and West Virginia. For the rest of us mostly east of the Mississippi, well, we will have to wait for another time.

We will explore much more about these remarkable creatures in upcoming episodes.
