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.

Probergrothius nigricornis is a species of bug found in tropical Asia. They feed primarily on the seeds of Malvales. The antennae are all black, the first and second segments nearly equal and the third is the shortest. The fore femora are serrate on the underside. P. sanguinolens which overlaps in distribution has the terminal antennal segment pale and the second segment longer than the first.

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.

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.
