Lady beetles (Coccinellidae)


There are 64 genera and 364 species of Coccinellidae described from Australia (Australian Faunal Directory, 2025)

A guide to the beetles of Australia by G. Hangay & P. Zborowski (CSIRO Publishing, 2010) lists the family's characteristics:

  • body broadly ovate, highly convex, usually glabrous but some finely pubescent, 1-7 mm in length
  • yellow to black, often bicoloured or spotted, some with metallic shine
  • head deflexed, concealed from above by prothorax
  • antennae short, usually 11-segmented, including a 3-segmented club
  • tarsal formula [number of tarsal segments on front, middle and hind legs] 4-4-4, but appears to be 3-3-3 as the third segment is minute and hidden

Adults and larvae of most species are predators of aphids, mealybugs, scales or other small insects and mites. Exceptions are Epilachna species, which are herbivorous on Cucurbitaceae and Solanaceae, and Illeis galbula which feeds on powdery mildews (Australian beetles, Vol. 1, eds. J.F. Lawrence & A. Slipinski, CSIRO Publishing, 2013)

@LisaH Hi Lisa, Yes keep the photo of the two but add the comment that it is for size comparison. :-) - Oh, which you have done.

Am just doing that - I took the photo of them both just for size context. I also couldn't reorder the photos on the app, so am on the laptop now to reorder. Do you mind if I still keep the photo of both lady beetles, but as a last photo?

@LisaH Hi Lisa, You have two different lady beetles here: Fungus eating and leaf leating. Could you please separate them.
Thanks
Alison

iNat thinks it may be 28-Spotted Potato Ladybird (Henosepilachna vigintioctopunctata).
