Dotted-lines Leaf Beetle - Paropsis ornata
Subfamily Chrysomelinae, FAMILY CHRYSOMELIDAE
This page contains pictures and information a bout Dotted-lines Leaf beetles that we found in the Brisbane area, Queensland, Australia.
- Body length 10mm
- We found this Leaf Beetle quite a number of time in mid summer. Found them once on Acacia and the others on Eucalyptus. The beetles were small to medium size, shiny bright, golden brown with dotted creamy-white lines on the back.
- Pictures taken in Mt Cotton early summer. Only one beetle was found on the young Acacia tree. Notice in the second picture a Leafhopper hiding at the back of the beetle.
- Later mid-summer in Karawatha Forest, we found this Leaf Beetle wandering on a gum tree.
- This beetle flied actively in the sunny hot day. .
- Usually a few of them can be found on host plant. Notice their bite marks on the leaves. Besides that no other damages were noticed.
- As all other leaf beetles, male and female look the same. Male may be a little bit smaller in size.
- When disturbed, this leaf beetle employs the drop to ground method to escape. So we usually put our hand under where the beetle sit when approach to the beetle. If drops onto the floor, the beetle will quickly run and hide under plant materials.
