Despite strong interest in pollinators and their services, there remain gaps in our knowledge as to how ants influence bee foraging decisions. Here, we characterized ant\u2013bee interactions at shared resources and the subsequent behavioral sequences exhibited by bees. We found that two-thirds of bumble bee (Bombus impatiens Cresson) behaviors at nectar resources involved direct interactions with Argentine ants (Linepithema humile Mayr). Consistent with predictions of interference competition, the number of ants at a shared resource decreased the probability of a bee feeding and increased the likelihood of a bee being bitten. Similarly, getting bitten by an ant decreased the probability that a bee would subsequently feed and increased the likelihood that a bee engaged in aggressive responses, such as gaping mandibles and attacking the ant. Behavioral sequences fell into two clusters: Cluster 1 was characterized by feeding and nonaggressive behaviors, and Cluster 2 was exemplified by strings of aggressive behaviors. Behavioral sequences that included aggression were longer and more diverse than those involving predominately nonaggressive behaviors, demonstrating that aggression (either on the part of the bee or the ant) extended behavioral exchanges and disrupted bumblebee foraging and resource collection. Our study identified that ant abundance and aggressive biting behaviors were strong predictors of subsequent bee actions. Such experiences may contribute to learned avoidance of ants in future encounters, consistent with interference competition theory, and have broader implications for disrupted foraging in social animals.<\/jats:p>","DOI":"10.1093\/jisesa\/ieaf076","type":"journal-article","created":{"date-parts":[[2025,7,31]],"date-time":"2025-07-31T11:44:24Z","timestamp":1753962264000},"source":"Crossref","is-referenced-by-count":2,"title":["Bees modulate behavior during nectar foraging in response to direct ant aggression (Hymenoptera: Apidae and Formicidae)"],"prefix":"10.1093","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4166-9061","authenticated-orcid":false,"given":"Michelle Constanza","family":"Miner","sequence":"first","affiliation":[{"name":"Conservation Education and Science Department, Arizona-Sonora Desert Museum , Tucson, AZ,","place":["USA"]},{"name":"Department of Entomology, University of California Riverside , Riverside, CA,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7741-113X","authenticated-orcid":false,"given":"Erin E","family":"Wilson Rankin","sequence":"additional","affiliation":[{"name":"Department of Entomology, University of California Riverside , Riverside, CA,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,11,7]]},"reference":[{"key":"2025110905444392200_ieaf076-B1","doi-asserted-by":"crossref","first-page":"20240628","DOI":"10.1098\/rsbl.2024.0628","article-title":"Risk-sensitive foraging in a tropical lizard","volume":"21","author":"Banerjee","year":"2025","journal-title":"Biol.
