Four-toothed Mason Wasp
Monobia quadridens
- Order & Family
- Order: Hymenoptera; Family: Vespidae
- Size
- 13 to 20 mm (approximately 0.5 to 0.8 inches)
Natural Habitat
Typically found in meadows, gardens, and woodlands; also residential areas near potential nesting sites like old wood, stems, or abandoned nests of other bees.
Diet & Feeding
Adults primarily feed on flower nectar for energy. Females hunt lepidopteran larvae (caterpillars) to provide as food for their developing offspring.
Behavior Patterns
Solitary wasps that do not live in colonies. Females build nests by partitioning existing cavities with mud. They are often active from late spring to early autumn and have a complete metamorphosis life cycle.
Risks & Benefits
Benefits the ecosystem naturally by controlling caterpillar populations and assisting in pollination. While they are capable of stinging if handled or threatened, they are generally non-aggressive towards humans and lack the nest-guarding drive of social wasps.
