Megalyra fasciipennisScott Richard Shaw
Megalyra fasciipennis is by far the most common and widespread of the Australian species. Large Australian megalyrids with banded wings and lateral tergal hair patches will usually belong to this species. This large wasp is found in Eucalyptus woodlands, where it attacks larvae of cerambycid beetles such as Phoracantha recurva (Hacker, 1913) in wood of old trees. The oviposition behavior was discussed by Rodd (1951). In Tasmania the species has been associated with several trees including Eucalyptus viminalis, E. ovata, E. vamaldulensis, Acacia dealbata, and Pinus radiata. This species was accidentally introduced to South Africa, presumably in imported lumber (Gess, 1964).
Megalyra fasciipennis is easily recognized by its large body size (11-20 mm), long ovipositor (7-13 mm), banded wings with black patch at the apex of forewing, fine areolate sculpture on the antero-lateral areas of the propodeum, and metasoma with lateral patches of silvery hairs. The species can be identified using the key provided by Shaw (1990).
