Ants are a common and recognizable group of insects, even by the non-entomologist. Familiarity can be attributed to their diversity (more than 14,000 species), abundance, and pestiferous nature. These factors support the idea that ants are fundamental components of ecosystem function. Ants participate in important ecological roles such as: turning soils, being major detritivores that influence brown food web function, serving as prey for other organisms, seed harvesting and distribution, and complex relationships seen by various levels of inquilines, slave-making and other social parasites. Given these interactions, ants are an excellent surrogate for understanding community structure and health. Such research is desperately needed as this region is under-surveyed regarding termite and ant diversity, distribution, and prevalence. These taxa were selected based on their significant roles in ecosystems, influences on human health, and economic impact. The ecoregion known as the Delmarva Peninsula includes the coastal plain of Delaware, Maryland and Virginia. This area has is highly fragmented due to massive urbanization and agricultural modifications. Additionally, this ecoregion is the southernmost distribution point for many northern species and, conversely, the northernmost distribution for typically southern species. This project determines the species richness and abundance for ants in the region, plots the distribution and seasonal patterns of surrogate soil fauna, and assesses the influence of exotic species. We have documented nearly all subfamilies found within the United States and, because no state list exists, have complied a foundational dataset for future studies. Documenting species assemblages is necessary to address avenues of research such as the effects of global climate change on native species distributions and the spread of invasive species.
