Larva During the larval stage, seven-spined woolcarder bee show rapid growth. They are worm-like, lacking true legs and wings, with a primary focus on feeding to accumulate energy for later transformations.
Pupal Entering the pupal stage, seven-spined woolcarder bee encapsulates itself and undergoes significant transformation. Its size increases, and within the chrysalis, tissues break down and reorganize into an adult body plan.
Adult Emerging from the pupa, the adult seven-spined woolcarder bee’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

Larva Seven-spined woolcarder bee larvae are typically located within nesting cavities, often in hollow stems or pre-existing holes in wood where the female has laid her eggs. To find larvae, look for nests in dead wood, plant stems, or bee hotels designed to attract solitary bee species.
Pupal Seven-spined woolcarder bee pupae remain inside the nesting cavities where they were larva, surrounded by a protective cocoon. To find pupae, one would need to very carefully open a nest in a non-destructive manner, which is not generally recommended due to the risk of disturbing or harming the developing bee.
Adult Seven-spined woolcarder bee adults can be observed foraging on flowering plants, particularly those that serve as good pollen and nectar sources. Look for adults in gardens with a variety of bee-friendly flowers, meadows, and other natural areas where wildflowers are abundant. Observing the patterns of flower visitation can help locate seven-spined woolcarder bee.
