A Selection of
Wasps, Bees and Ants from
Arizona's Sycamore Canyons

Arguably, the Hymenoptera, the order that comprises the wasps, bees, and ants, is the most important order in the ecology of the Sycamore Woodland ecosystem. The majority of the flowering plants rely on the bees for pollination services. Ants are ubiquitous on every plant and every square meter of soil. Wasps, most of which are too small to be noticed by the casual observer, keep many of the plant-feeding insect populations in check through parasitism.

Hymenoptera have two pairs of membraneous wings in the adult stage except in wingles ants. There are always four life stages with complete metamorphosis: egg, larva, pupa and adult. In other words small wasps or bees do not grow into bigger ones.
