- Jewel Bugs and Shield-backed bugs are plant suckers. They
can be distinguished from other bugs by their scutellum completely covered the
whole abdomen and wings. This is why sometimes they are miss-recognized as beetle. They
are easily distinguished from beetles by having sucking mouthparts
and the shield on the back is continuous, not the divided wings cover with separation
at the middle.
- This family are closely related
to stink bugs (Family Pentatomidae). They also produce offensive odors when disturbed.
