This beetle was found on the wall outside a house in a backwater town. Their natural habitats are often forests and places with unadulterated vegetation; this one probably was found in a town due to the destruction caused by mankind.

Esse besouro foi encontrado em um muro de uma casa em uma cidade de interior. Seus habitats naturais são normalmente florestas e áreas de mata; esse foi encontrado na cidade provavelmente graças à destruição dos habitats naturais causada pelo ser humano.


Esse impressionante e gigante besouro é um Acrocinus longimanus, um membro da ordem Coleoptera, subordem Polyphaga, infraordem Cucujiformia, superfamília Chrysomeloidea, família Cerambycidae, subfamília Lamiinae e tribo Acrocinini.

O tamanho do corpo desse besouro pode chegar a 9cm. As pernas próximas ao pronotro são geralmente o dobro ou mais do tamanho do corpo. O sujeito retratado é um macho.

São amplamente distribuídos no Brasil, onde suas larvas alimentam-se de Ficus sp. (ordem Rosales, família Moraceae e tribo Ficeae; "figo"), Artocarpus sp. (ordem Rosales, família Moraceae, subfamília Artocarpoidea e tribo Artocarpeae; "jaca") e algumas plantas silvestres como Coussapoa sp.. O nome popular "arlequim" do Acrocinus longimanus vem da coloração da criatura e da cabeça, pronotro e élitros ornamentados. As fêmeas produzem cerca de 160 óvulos; os ovos são ovipositados em troncos de árvores. O estágio pupa dos machos demora 10% a mais do que o estágio pupa das fêmeas. Os adultos alimentam-se da seiva de árvores.

Após depositar os ovos, o besouro adulto cava um sulco ao redor do ramo, que eventualmente morre e cai ao chão, onde as larvas irão se alimentar e se desenvolver. Ao emergirem, as larvas irão se alimentar do galho, até que o ciclo de crescimento se complete.


This impressive, gigantic beetle is an Acrocinus longimanus, a member of the order Coleoptera, suborder Polyphaga, infraorder Cucujiformia, superfamily Chrysomeloidea, family Cerambycidae, subfamily Lamiinae and tribe Acrocinini.

This beetle's body size can reach 9cm. The legs are usually twice the size of the body or more. The subject portrayed is a male.

They are widely distributed in Brazil, where their larvae feed on Ficus sp. (order Rosales, family Moraceae and tribe Ficeae; "fig tree"), Artocarpus sp. (order Rosales, family Moraceae, subfamily Artocarpoidea and tribe Artocarpeae; "jackfruit") and a few wild plants such as Coussapoa sp.. The popular name of Acrocinus longimanus "harlequin beetle" comes from the creature's coloring and ornamented head, pronotrum and elytra. Females produce around 160 ovules; the eggs are oviposited on tree trunks. Males' pupae take 10% longer than females'. Adults feed on the sap of trees.

After laying the eggs, the adult beetle carves a deep incision around the branch, which proceeds to die and fall on the ground, where the larvae will feed and develop. Upon emergence, the larvae will feed on the log, until the growth cycle is complete.

Post updated with two videos, had to post them in the description because the Youtube section wasn't allowing me. Both videos were made by me.

Leuba Ridgway, it's no trouble at all, I just have to find the time to do it, the video is in my notebook and it's gone for maintenance. Once it is back I'll upload it to youtube and then post a link here. I'll shoot a comment here when that's done. Have a good night everyone and sleep well. I've spent the last few days editing all my posts to include acceptable habitat information as suggested and I provided the size / wingspan of every creature and also their sex when I knew. There are a few posts that still need editing, but those will be done tomorrow. Sleep tight!

Thanks Oscar. That would be great - I am sure everyone would love to see it, if it's not too much trouble.

Leuba Ridgway, I actually have a video of it walking, opening up the elytra and flying away. I will post it on Youtube in the coming days and provide the link in this post's "Youtube Video" section.

Would love an outfit like the beetle's. Great specimen.

If you have a far shot of the beetle with the legs included, it would be good to see that as well. Thanks for sharing this Oscar.
