Here in Indiana, the cold temperatures, snow, howling winds and lack of food have forced beetles into overwintering sites. Down Under, Summer has just begun and Christmas there is greeted by summer insects. Scarab beetles in the genus Anoplognathus are collectively known as “Christmas Beetles”. The larvae of these beetles spend the majority of their life underground. In late spring they emerge and begin mating and feeding on tree foliage. Many of the species have bright colors, tiny natural ornaments that “decorate” the trees. These beetles are featured by CSIRO as one of their wall papers.

I wonder if any pyrgotid flies parasitise them? I’d really like to describe a “Christmas fly” reared from the Christmas Beetle…
Several dozen Pyrgotid species are known from Australia. I don’t know if any are from Christmas Beetles.
