Venom is biochemical solution many animal lineages have converged upon to "punch up" and meet their needs. These complex toolkits are often contextualized as weapons to maim or kill, but this is not always true. In the ant genus Megalomyrmex, venom in the form of alkaloids plays a critical role in the context of social parasitism. This dissertation explores the evolution, function, and molecular underpinnings of venom within Megalomyrmex through. Chapter 2 reconstructs the phylogeny of Megalomyrmex using ultraconserved elements and investigates evolutionary transitions in venom chemistry across the genus, revealing that while certain alkaloids are most prevalent in social parasites, no venom compound is unique to them. Chapter 3 quantifies physiological venom investment and insecticidal potency across ecologically distinct species, finding that social parasites invest more in venom volume, but not necessarily in toxicity, highlighting that ability to disperse venom is as important as functional profile. Chapter 4 is a novel approach to Megalomyrmex venom characterization, which has primarily focused on alkaloids, by utilizing transcriptomics to describe venom transcripts within Megalomyrmex milenae. uncovering a diverse suite of venom-associated proteins previously undescribed in this genus, including allergens, pore-forming toxins, and neuroactive peptides. Collectively, these findings challenge the narrative of Megalomyrmex venoms as simple alkaloid systems and demonstrate the evolutionary dynamism of venom as a key innovation. This work underscores the importance of integrating phylogenetic, ecological, biochemical, and genomic approaches to understand the evolutionary ecology of venom and illuminates the broader roles venom plays in niche specialization and social evolution.
