Sometimes mistaken for the Bald-Faced Hornet, the Four-Toothed Mason Wasp is not nearly as social.





The solitary Four-Toothed Mason Wasp is a beneficial insect to have in the garden, just like its doppelganger, the Bald-Faced Hornet. The Mason Wasp reduces the number of leaf-rolling caterpillars by using them as food for their newly hatched larvae.

Females will create a nest in an abandoned hole created by a Carpenter Bee, Mud Dauber, ground nests from another species of bee or they will use hollow tubes (plants, pipes, hollowed branches). Once the location is determined, she creates cells in it where she will lay her fertilized eggs. She then begins to hunt and paralyze a variety of moth and cutworm caterpillars. She brings them, alive, back to her nest and puts a few in each cell and plugs the cell up with mud.

Hatched larvae begin feeding on the living caterpillars in their cells. After a few days of growing, a larva will pupate in the cell. Some late season larvae will overwinter as pupae. After pupating, it will eventually chew through the mud and free itself from the cell. Adults drink flower nectar. They are most active in the summer and usually found in gardens and meadows.

Ant, Bee and Wasp Anatomy
Graphic showing basic anatomy of both a bee and an ant insect
1
Antennae: Ants and Bees both have a pair of antennae on the head that senses their surroundings.
2
Head: The head contains the insect's compound eyes, antennae, and mandibles.
3
Thorax: Contains various vital parts such as the aorta and nervous system.
4
Abdomen: Contains various organs including the heart, gut, venom glands, and anus.
5
Legs: Ants and Bees have three pairs of legs attached to the thorax (center-body section).
NOTE: Ants, Bees and Wasps are part of the Hymenoptera order because they share many similarities.


Territorial Reach (A-to-Z)
Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed below as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections below indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.

Territorial Area Map (Visual Reference Guide)
The map below showcases (in red) the states and territories of North America where the Four-Toothed Mason Wasp may be found (but is not limited to). This sort of data can be useful in seeing concentrations of a particular species over the continent as well as revealing possible migratory patterns over a species' given lifespan. Some species are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America.
