A small and dynamic terrestrial insect, dindymus brevis often occupies warm, arid environments where it feeds primarily on the seeds of herbaceous plants. Specifically adapted to such dry habitats, it has developed an efficient reproductive strategy with females laying eggs that can withstand periods of drought. As a nymph, its vibrant coloration warns potential predators of its unpalatability, a trait that persists into adulthood along with the development of wings, which facilitate not only flight but also the emission of distinct ultrasonic signals used in communication and mate attraction.

Scantius aegyptius, the Mediterranean red bug, is a species of red bug in the family Pyrrhocoridae. Considered an invasive species in North America, it was discovered to have made its first appearance in America on June 13, 2009 by Doug Peltz, the American science communicator.

Named for its striking pattern, european firebug is often described as the "firebug." It is known to congregate in large aggregations reaching as many as one hundred individuals at a time, particularly while still immature. Because they feed upon the seeds of lime trees, clusters of mating individuals can often be found at the bases of these trees in late spring.

Resplendent in its contrastingly patterned exoskeleton, dysdercus poecilus can be observed with distinctive red and black markings across its back, an adaptation that serves both as a warning to predators and a mechanism for mate attraction. This species is known for its unique puncturing and sucking mouthparts, demonstrating a preference for the seeds of malvaceous plants as nourishment, which they access using specialized enzymes to break down complex plant tissues.

The nymphs moult five times as they grow. The first and second instar nymphs are orange/red, and the third instar has emerging wingpads and is orange at first, deepening in colour by the second day. The fourth instar is crimson and cylindrical with larger, darker wingpads and the fifth instar is similar, with prominent dark wingpads, black antennae and legs. The adult insect is also crimson, with a pair of black spots on the forewings. The membranous hind wings are concealed under the forewings when the insect is at rest. Males are about 14 mm (0.6 in) in length and females are a little larger.
