Data for Aphid Infestation and Monarch Butterfly Oviposition in Urban Gardens

These data records weekly aphid and monarch butterfly (Danaus plexippus) neonate counts on individual milkweed plants in multiple raised garden beds in Chicago during the summers of 2023 and 2024. Relationships between aphid infestation and monarch neonates can be investigated along with weekly trends of monarch oviposition and aphid abundances. All gardens included in this study were on the University of Illinois Chicago campus, and within 100 meters of proximity. Data are provided on three milkweed species in 2023, and one milkweed species in 2024.
