Trichiotinus rufobrunneus
Florida flower scarab
Trichiotinus rufobrunneus is a species of flower scarab beetle endemic to Florida, commonly known as the Florida flower scarab. It belongs to the genus Trichiotinus, a North American endemic group of trichiine scarabs. The species is associated with the flowers of Opuntia australis (Florida pricklypear cactus), an endemic plant, and has been observed mating within these flowers. Its distribution is limited to Florida, making it a species of conservation concern due to habitat loss from urban development and agriculture.
Trigonopeltastes delta
delta flower scarab, D beetle
Trigonopeltastes delta is a diurnal scarab beetle in the subfamily Cetoniinae, commonly known as the delta flower scarab or D beetle. Adults measure 8–10 mm in length and are distinguished by a prominent yellow triangle on the pronotum that resembles the Greek letter delta, giving the species its name. This marking has been theorized to function in Batesian mimicry of wasp defensive coloration. The beetle is native to the southeastern United States with range extending north to New Jersey, and is frequently observed on flowers from late spring through summer.
