海神大兜蟲(原名亞種)簡介

中名: 海神大兜蟲(原名亞種)/黑長戟大兜蟲 學名: Dynastes neptunus neptunus 產地: 哥倫比亞

本種有著猶如太刀般俐落的頭角,以及有如羅馬神話當中海神涅普頓的三叉戟一樣的三支胸角,因而得名海神大兜蟲。亦有人認為其酷似同屬而不同種的長戟大兜蟲,因而亦得別名黑長戟大兜蟲。

本種分別有兩個亞種:原名D.n.neptunus 亞種以及D.n.rouchei亞種。而本次介紹的就是較為大型及常見的原名亞種,基本上在市面上看到原產自哥倫比亞或厄瓜多爾的皆為原名亞種。

飼養方面,由於本種在原產地棲息於高海拔的山林中,故飼養溫度建議保持在28攝氏度以下,否則有機會導致熱衰竭而死亡,理想溫度為20-24攝氏度。基本上只要控制好溫度的話,繁育飼養上就與一般長戟大兜蟲無異,非常簡單,只是幼蟲期會較長,約為兩年。

值得一提的是,與近親撒但大兜蟲一樣,本種成蟲足跗節的勾爪猶如倒勾一樣,弧度會比同屬的長戟系和白兜系蟲種大,而且整個腿部的長度比例較短。推測是成蟲在原產地偏向地棲,主要在地上的落葉堆中活動,攀爬力較弱,故比較少爬到較高的樹上。這也意味著,在把玩本種成蟲的時候,盡量不要離地太高,否則稍一不慎掉落就會令蟲體受傷,嚴重者更有機會會斷角收場,這點請務必注意。

This species has a samurai-sword-like head horn, and three pronotal horns, resembling the trident of Neptune, the sea god in Roman mythology.

There are two subspecies of the Neptunes beetle: D.n.neptunus and D.n.rouchei. In these pictures, is D.n.neptunus, the relatively large and common subspecies among the two of them. Basically, the subspecies that originated from Colombia or Ecuador are all D.n.neptunus on the market.

In terms of breeding, since this species inhabits high-altitude woodlands, the breeding temperature is recommended to be kept below 28 degrees Celsius, otherwise it may cause heat exhaustion and hence death of the beetle. The ideal temperature is 20-24 degrees Celsius. As long as the temperature is well controlled, the breeding will be no different from hercules beetles, but only with a longer larval stage, approximately two years.

It is worth mentioning that, like its close relatives, D.Satanas, the curvature of its claws are higher than that of the other members of Dynastes, the ratio of the length of the limbs are shorter too. It is speculated that the adults tend to dwell in the fallen leaves on the ground. The climbing ability is relatively weak, therefore they seldom climb to higher trees. When handling the adult of this species, try not to raise the beetles too high above the ground, otherwise they will be injured if they fall accidentally. Please be aware of this.
