features
The medium-sized blue-black bugs have yellow, orange or red spots on the three corners of the scutellum, which spots can mix together. The males grow up to 12 mm long, while the females reach a body length of 17 mm. The connexive (part of the abdomen that is visible on the side) is also colored yellow, orange or red. The sides of the pronotum each have a thorn. The blue-black nymphs have a red abdomen.
Occurrence
Euthyrhynchus floridanus occurs mainly in the Neotropics . Their range extends over the southern United States and extends in the north to Pennsylvania . The species is also found in Central America and South America (Brazil).
Way of life
The bugs predatory feed on arthropods . The prey animals include various beetles and their larvae, caterpillars, cicadas and spiders as well as representatives of the related phytophagous stink bugs of the subfamily Pentatominae . For this reason, the bug species is considered a beneficial insect . The nymphs show a gregarious behavior . They attack several larger prey animals.
The clutch size of Euthyrhynchus floridanus usually consists of 20 to 90 eggs. The development of the bug includes five nymph stages. The entire development period, beginning with the egg-laying, amounts to an average of about 100 days, with a third of the time elapsing until the nymphs hatch. The species bivoltin occurs in Florida .
