However, some of them look similar and hard to be identified. They are mostly from
10 to 25mm in body length.

 - Coreid bug eggs
-
- Family Coreidae can be distinguished from the Lygaeidae
by their forewings which have dense longitudinal parallel veins. Coreidae has head narrower and most often shorter than pronotum, which
can be distinguished from
Alydidae have a head that is nearly
as wide as and as long as the pronotum. Most of them have two ocelli. They
are medium to large in size.
-
- Coreid Bugs are generally medium to large in size. Some species in this family with hind legs expanded and somewhat leaf-like, and those are commonly called Leaf Footed Bugs.
Their antennae are four segmented.
-
- Some species in this family called Tip Wilters because they suck out the
plant juices just below the tip of a new branch causing it to droop and wilt
soon afterwards. They are common pest species in many crop plants as well as garden
plants and
vegetables.
-
- Coreid adults are relatively slow moving and are seen on the tips of shoots.
Nymph stages are fast moving. All of them are with strong repellent odors.
