This strange little wasp was drowning in a tank of rainwater. After scooping it out it gradually came back into action on a paper towel and turned out to be an unusual type.
About 15mm long overall. An unusual sectioned, tapered abdomen which seemed very flexible.
Suburban back yard. Very cold damp conditions.
A unusual wasp family with only one genus with only 3 species in Australia. Monomachus antipodalis is the only species found in Victoria.
