In India plants visited by X. pubescens for pollen are Cochlospermum religiosum, as well as Peltophorum, Cassia and Solanum species.
Those visited for nectar include Calotropis, Bauhinia, Crotalaria, Anisomeles, and Gmelina species and some other plants.

In the Mediterranean the most common plants visited by X. pubescens for both pollen and nectar are Helianthus annuus, Parkinsonia aculeate, Luffa aegyptiaca, as well as Lonicera species.

In Israel, the ranges of X. pubescens and X. sulcatipes overlap, leading to competition between the two species for plants to forage on.
Both species visit Calotropis procera only for nectar, Retama raetam for both pollen and nectar, and Lucaena only for pollen.
Because X. pubescens has a minimum ambient temperature for activity of about 18 degrees Celsius while X. sulcatipes has a minimum ambient temperature of 21 degrees Celsius, X. pubescens can begin foraging earlier in the day than X. sulcatipes.
This allows X. pubescens to get to flowers first, but then after X. sulcatipes begins foraging, it becomes the dominant bee.
The bees can recognize when a flower has been previously visited by a bee of either species, and will proceed to avoid that flower.
