Size
7-40 mm, typically 10-20 mm; NA members up to 30 mm
Identification
Medium to large, often dark-colored bugs with many parallel veins on front wing membrane (Alydidae have similar venation but their heads are nearly as wide and long as pronotum)
Family characteristics:
antennae 4-segmented
ocelli present
beak 4-segmented
front wing membrane with many veins (visible at rest)
tarsi 3-segmented
abdominal margin in many species raised--the folded wings lying in the depression formed by the margin(3)
scent glands on the thorax between middle and hind coxae
head narrower than and often shorter than the pronotum
hind tibiae in some have leaf-like expansions (e.g., Acanthocephala, Leptoglossus); in some (e.g., Chariesterus) antennal segments are similarly expanded

Keys to FL species in(6)
Range
Widely distributed but most diverse in the South and Southwest
Food
all are plant feeders(3)
Life Cycle
Eggs are typically cemented beneath foliage of host. One or more generations per year. Adults sometimes overwinter.
Remarks
When handled or molested, often give off an unpleasant odor, a defensive secretion of the thoracic glands(7); active compounds -- mostly straight-chain aldehydes and ketones, of which trans-2-hexenal is perhaps one of the most common -- quite similar to those of the stink bugs, Pentatomidae(8)
A few species are agricultural pests
Often parasitized by tachinids (examples)
