Black and yellow mud dauber

Sceliphron caementarium

A species of Mud daubers, Also known as Black-and-yellow mud-dauber wasp, American mud-dauber wasp

The species name Caementarium is Latin for "mason", which comes from the black and yellow mud dauber's practice of building nests out of mud. The female wasps prey on spiders, fill cells of the nest with both the prey and her eggs, and leave the nest when it is full. When the larvae hatch, they eat the prey and leave the nest as well.

Habitat Preferences of Black and yellow mud dauber Through Different Life Stages

The black and yellow mud dauber, known as the mud dauber, undergoes complete metamorphosis. Adult black and yellow mud dauber can typically be found hovering around flowers, buildings, or under eaves. To locate nests where eggs are laid, look along sheltered locations like garages, sheds, or attics. For the larvae, search inside these mud nests, as they are sealed and provisioned with spiders by the female black and yellow mud dauber. Pupation also occurs within these nests. When searching for emerging adults, revisit the nests in warmer seasons, as this is when mature black and yellow mud dauber chew their way out.

When is the Best Time to Observe Black and yellow mud dauber

Early morning or late afternoon, when black and yellow mud dauber are most active and temperatures are milder.

What is the Best Weather to Observe Black and yellow mud dauber

Warm and dry conditions are ideal, as black and yellow mud dauber do not favor rainy or cold weather.

How and Where Can You Find Black and yellow mud dauber at Different Life Stages

Adult Black and yellow mud dauber adults are known for their mud-nest building behavior. To find them, look for their distinctive nests on sheltered building sides, under eaves, inside barns, or on other structures. Watch for black and yellow mud dauber gathering mud or returning to their nests during warmer parts of the day.

Larva Black and yellow mud dauber larvae reside inside protective mud cells provisioned with spiders or insects to eat. Discovering these cells, typically adhered to sheltered surfaces, can lead to finding black and yellow mud dauber larvae. Cells are sometimes exposed if nests are constructed in less concealed places.

Pupal Black and yellow mud dauber pupate within their individual cells in the nests. Locating a nest will allow you to find black and yellow mud dauber in the pupal stage. If safe and ethical, one might carefully open a nest cell to observe the pupa, though this should be done minimally to avoid harming black and yellow mud dauber.

Human Stinging

Toxic to Humans

Black and yellow mud dauber has a mild venom that it can deliver through its sting, used primarily for subduing prey rather than defense. Due to the mild nature of the venom, the toxic impact on humans is typically minor, resulting in temporary pain, redness, and swelling. Serious long-term effects or severe complications are rare, with most cases resolving without medical intervention.

Toxic to Animals

Black and yellow mud dauber typically poses a mild threat through its sting, which can cause discomfort among a range of animals, including humans and various domesticated animals such as dogs, cats, and horses. When stung, these animals might experience pain, swelling, and allergic reactions, although it generally isn't severe. The risk is greater for individuals with sensitivities to such stings. Birds might be disturbed by black and yellow mud dauber but tend to suffer less due to their quick avoidance behavior.

Does the Black and yellow mud dauber sting humans?

Black and yellow mud dauber typically reserve stinging for prey and self-defense. Human stings are rare, occurring primarily when they feel threatened. Only female black and yellow mud dauber possess a stinger, which doubles as an egg-laying organ. A sting generally causes mild pain and swelling for humans, with no significant impact on the black and yellow mud dauber itself.
