About Occidentalis Elephant Beetle

A large elephant beetle from Mexico's Pacific coast, known for its sideways-jutting horn and pale coloring. Males reach over 127mm; larvae take 2–3 years to mature. Best suited to intermediate keepers.

7 things to know before welcoming a Occidentalis Elephant Beetle

1. 1Males Reach Over 127mm

   Males grow to 70–127.2mm while females reach 45–75mm, a sizable gap between the sexes. Only males develop the prominent horn, which becomes fully visible once they reach adulthood.

2. 2A Long Larval Stage

   The larval stage typically lasts around two to three years (a general figure for the genus), much longer than their time as adults. Raising one calls for patience while you watch that slow growth unfold.

3. 3Suited to Intermediate Keepers

   This species is generally considered suitable for intermediate keepers. Having some prior experience raising beetles makes day-to-day care noticeably easier.

4. 4Once Considered a Subspecies

   This beetle was once classified as a subspecies of the Elephant Beetle but is now recognized as its own species. It's native to Mexico's Pacific coast.

5. 5A Sideways-Jutting Horn

   A thorax horn that juts out sideways in a bold, distinctive shape is this beetle's signature trait. Its notably pale body color also sets it apart from other elephant beetles.

6. 6Caution When Keeping Multiples

   Large males may use their horns to jostle with one another, so care is needed when housing multiple males together. Keeping them individually avoids this concern altogether.

7. 7Prepare Before You Bring One Home

   Since adults grow quite large, it's worth preparing a roomy enclosure in advance. With a larval period of two to three years, it's also worth confirming you can commit to their care over the long haul before bringing one home.
