Periodical cicada Brood IX (9) will emerge in the spring of 2020 in North Carolina, Virginia and West Virginia. The last time this brood emerged was in 2003.
What, when, where, and why:
- Millions of these:
- Cicada insects with a 17-year life cycle.
- Some people call them “locusts” but they’re really cicadas.
- Which species: All three 17-year species, Magicicada septendecim, Magicicada cassini and Magicicada septendecula. How to tell the difference between the species.
- NOT the green ones that arrive annually.
📅🌡️ When: Typically beginning in mid-May and ending in late June. These cicadas will begin to emerge approximately when the soil 8″ beneath the ground reaches 64 degrees Fahrenheit (Heath, 1968). A nice, warm rain will often trigger an emergence.
Other tips: these cicadas will emerge after the trees have grown leaves, and, by my own observation, around the same time Iris flowers bloom.
