ESM 1. Two-way clustering showing two main groups of nests (A and B) and four groups of

pollen types (1 to 4). Values of the matrix indicate percentage of the pollen grains per nest.

ESM 2. Comparison between the number of floral records obtained by floral visitation and

pollen analysis methods for Augochlora amphitrite, A. alexanderi, A. esox and A. isthmii.

Ribera Norte. Sawdust and one egg can also be seen.
