This distinctive genus is named for its superficial resemblance to the African Buprestid genus Julodis. The adults are short-lived and often appear in large numbers in mallee areas of SA from late November to mid-December.

Bellamy & Weir 2008 reinstated Julodimorpha saundersii, dividing the genus into a western and eastern species, although the geographical boundary between them was not precisely established. The western species, J. saundersii, at least, is famous for the habit of males congregating on and attempting to mate with discarded stubbie beer bottles which have a similar colouring and stippled texture to the beetles.

There are many SA Museum specimens of this species that have not yet had their data captured.

Host plant notes

Larvae are believed to feed on roots and Hawkeswood & Peterson 1982 cite a WA collection of a beetle ovipositing 2.5 cm below the ground near the base of a Calothamnus shrub.
