| | Pollen | | Pollen is a floury substance, produced by seed plants. It consists of single grains (microspores) with a resistant wall (sporoderm). The sporoderm has an inner (intine) and an outer (exine) structure.

It nests in pre-existing holes in earth, masonry or wood. The females build individual cells for their eggs using pieces of leaves bound together by a substance they secrete. They then supply each cell with pollen or nectar, before introducing an egg into the cell. After egg-laying the cell is sealed. When the larvae hatch, they live on the pollen and nectar for weeks before pupating. The Anthidium... | | |
| | Mature larvae are able to secrete a substance which drives away their competitors ,especially adult beetles of the same species, from the leaves of the forage plants. At the end of the third larval stage, the larvae dig down into the soil to a depth of about 2cm and pupate. After 6-9 days th... | | |

The yellowish-white eggs are glued together inrings, using an adhesive brownish substance, onto the stems of plants such as common sorrel, sheep's sorrel (Rumex acetosella), field sagewort, ribwort plantain (Plantago lanceolata), Achillea, andworts (Minuartia), heron’s bill (Erodium), blackberry (Rubus), and Agropyron or dwarf everlast (... | | |
