The organ pipe mud dauber (Trypoxylon politum) is a predatory wasp in the family Crabronidae. It is fairly large, ranging from 3.9–5.1 cm, and has been recorded to fly from May to September. Females and males are similar in colour, a shiny black, with the end part of the back leg being pale yellow to white.[1] The organ pipe mud dauber feeds mainly on three genera of spider: Neoscona, Araneus, and Eustala.[2] Melittobia, a parasitoid wasp, is a common ectoparasite of T. politum prepupae.[3] Other sources of parasitism include the bombyliid fly Anthrax, chrysidid wasps, and various species of scavenger flies (Miltogramminae).[4] The tufted titmouse (Parus bicolor) is a known predator of T. politum, and may feed on them more commonly than previously thought, as the holes made by the titmouse are similar in shape and size to those made by T. politum leaving the nest after pupation.[5]

Organ pipe mud daubers are also an exceedingly docile species of wasp, and generally beneficial to have around, as they serve to keep spider populations down; larvae feed on living paralyzed spiders. [6]
