The Blue Mud Wasp reaches 15-25 mm in length. It displays a striking metallic blue to blue-green body with iridescent sheen. Wings appear smoky dark. The slender waist and robust thorax aid agile flight. Legs show black with subtle blue highlights. This vivid coloration distinguishes it from black mud daubers.
This wasp inhabits open areas, gardens, and human structures across most of North America except the northern Great Plains. It favors spots with mud sources and spider prey near buildings, bridges, or rocks. Nests often attach to walls or eaves in urban and rural settings.
Females take over old mud dauber nests or build new ones, stocking cells with paralyzed spiders, primarily black widows. They sting prey to immobilize, providing fresh food for larvae. Adults sip nectar from flowers. Solitary and non-aggressive, they rarely sting humans unless handled.
Females provision and seal cells in spring to summer. Eggs hatch into larvae that consume spider provisions over weeks. Pupation occurs in cocoons within cells. Adults emerge to continue the cycle. One to two generations complete yearly, with prepupae overwintering in colder regions.
Highly beneficial, the Blue Mud Wasp controls black widow spiders, reducing venomous bites near homes. It repurposes existing nests without damaging structures. No pest status; it supports natural pest management safely.
This preserved specimen highlights the stunning metallic blue body, ideal for wasp education and displays. Check it out on BugGuide! https://bugguide.net/node/view/5458
