Taxonomic Note
There is conflicting authorship information in sources: Motschulsky, 1845 is accepted by GBIF and NCBI, while Say, 1823 is cited in Catalogue of Life as an ambiguous synonym. The has only 35 observations on iNaturalist, indicating it is not frequently encountered or recorded.
Research Methodology Context
A. limbatum was specifically identified in University of Georgia research using clay decoy models to assess activity in turfgrass. This method reveals predator presence through distinctive bite marks, with predators leaving paired punctures, deep distortions, and U-shaped marks on caterpillar-shaped models.
