This page contains pictures and information about the Red Eyes Bugs that we found in the Brisbane area, Queensland, Australia.

The bug has bright red eyes and red abdomen. Its thorax and front wing covers are reddish-brown in colour. Its legs and antenna are all on black. The L. mitellata and L. tagalicus are looked exactly the same and it is almost impassable to distinguished them in photo.

The nymph looks similar to the adult bugs except their wings are not fully developed. We found a number on them, including nymphs and adults, on the Lantana plants during early summer. When disturbed they hided on the other side of the leaf.
