We found leafmines of Phytomyza ditmani on Ilex decidua (Possumhaw) in Craighead County, AR, in the spring of 2023. We collected larvae and pupae of P. ditmani in the field and reared them in the lab to obtain adult forms. Through genetic sequencing of a barcoding gene, we confirmed the identity of the flies as P. ditmani. To our knowledge, this is the first confirmed record of P. ditmani in Arkansas and the mid-south region of the US.
