Dynastes hercules (Linnaeus, 1758) Coleoptera, Scarabaeldae, Dynastinae - hercules beetle

It belongs to the subfamily Dynastinae, family Scarabaeidae, which is represented in Brazil by ca. 1,800 species.

The Dynastinae are the largest known scarsabaeids and can measure over 150mm long . They display a conspicuous sexual dimorphism and males have projections, tubercles and horns on the head and the pronotum with generally extravagant shapes.

Dynastinae larvae, commonly known in Brazil as "pão-de-galinha" or "torresmo", feed upon roots or decayed vegetable matter inside the soil. Adults are attracted by light and - depending on climatic conditions - hundreds of them can be found around one single light source.

The genus Dynastes comprises four neotropical species. D. hercules - one of the greatest ones - can be found in the forest areas from Central America to Brazil (Bahia state) and in the Lesser Antilles. Adults live about six months and feed upon decayed fruits. Males - with huge horns - engage in spectacular battles and sometimes one of the contenders can be cut in the middle. Larvae live on decayed wood and the larval cycle lasts around 20 months.

 

Dynastes hercules (Linnaeus, 1758)
Coleoptera, Scarabaeidae, Dynastinae-"besouro-hercules".
Pertencente à subfamília Dynastinae da família Scarabaeidae que está representada no Brasil por ca. 1.800 espécies.

Os Dynastinae são os maiores escarabeídeos conhecidos e podem ultrapassar 150 mm de comprimento. Apresentam acentuado dimorfismo sexual e os machos ostentam na cabeça e no pronoto projeções, cornos e protuberâncias com formas geralmente extravagantes.

Larvas de Dynastinae, vulgarmente conhecidas como "pão-de-galinha" ou "torresmo", alimentam-se de raízes ou matéria vegetal em decomposição no interior do solo. Os adultos são atraídos à luz e, dependendo das condições climáticas, centenas deles podem ser atraidos a uma fonte luminosa.

O gênero Dynastes congrega quatro espécies neotropicais. D. hercules uma das maiores ocorre nas áreas florestais da América Central ao Brasil (Bahia) e nas Pequenas Antilhas. A vida dos adultos dura aproximadamente seis meses; alimentam-se de frutos em decomposição. Os machos com suas pinças enormes travam batalhas espetaculares e, às vezes, um dos contendores pode ser secionado ao meio. As larvas nutrem-se de madeira em decomposição e a duração do estágio larval é de cerca de 20 meses.
