Periodical cicada update for La.

This year, from early-May through early June, Louisianans could potentially witness the emergence of periodical cicadas, as the 13-year cicada Brood XIX is scheduled to make an appearance in northern Louisiana.
Historical records indicate the parishes where they may be found are Caddo, Claiborne and Webster. Lack of documentation of the previous emergence in the state has led to concerns about Brood XIX’s potential extinction.
Amidst uncertainty about the fate of Brood XIX, we call on citizen scientists to aid in documentation efforts. By photographing the cicadas and uploading photos to iNaturalist, a social networking site that helps map biodiversity worldwide, this would provide new information on the distribution and survival of the Brood XIX cicada population.

In addition to the 2024 emergence of Brood XIX, two additional 13-year broods will be emerging during the coming years: Brood XXII during 2027 and Brood XXIII during 2028. Both of these broods cover a large area of eastern Louisiana and have been documented as far south as Baton Rouge.
