Identification of spotted lanternfly individuals through photographs

As 2023 comes to an end, iEcoLab is taking the time to reflect on notable research produced this past year. During her time as a post-doctoral fellow, Dr. Nadege Belouard along with Dr. Jocelyn Behm investigated a new technique researchers can use to identify spotted lanternfly individuals. In the publication titled, “Spotted! Computer-aided individual photo-identification allows for mark-recapture of invasive spotted lanternfly (Lycorma delicatula)”, Belouard & Behm determine the effectiveness of software I3S to identify previously photographed¬† individuals. The software allows the user to upload a photo of an organism and mark unique spots on an individual, like spotted lanternfly. Through lab validation, the software proved to be 100% reliable to identify an individual spotted lanternfly. When tested in the field, of 89 individuals originally photographed, 31 were recaptured 4 hours later. The novel technique to track individual spotted lanternfly demonstrates promising potential to be used in field and lab experiments to inform management of the invasive insect.
