Flores rhino beetle care sheet

Adults:

  • Size: 40-80mm
  • Adult life span once active: 2-5 months
  • Temperature: 70-80°F
  • Humidity: 60-70%
  • Food: Beetle jelly or fruits(no citrus)

Breeding:

  • Required temperature for breeding: 70-80°F
  • Minimum container size for egg laying: 8 in x 4 in x 8 in. Bigger containers are always the better option for breeding!
  • # of eggs laid on average: 30-60 eggs.
  • Flake soil humidity adjustment: The amount of water is appropriate when you can form a ball by squeezing the flake soil with your hand. Water seeping out of your hands during the process indicates that there is too much water.
  • Set-up: Pack the bottom 5cm of the container tightly and fill up the remaining space loosely with flake soil. Place objects such as sticks or barks at the top so that the beetle can flip itself over if needed. Lastly, don't forget to regularly change fruits or beetle jelly for the beetle to feed!

Larvae:

  • Food: Flake soil or white-rot hardwood.
  • Temperature: 70-80°F
  • Humidity: 60-70%
  • Larval duration: 10-14 months.
  • Container size recommendations:
    • L1: 4oz deli cup
    • L2: 16oz deli cup
    • L3/pupa: 32oz deli cup

Additional insights:

  • Larvae of the genus Xylotrupes are easy to care for, as they can thrive on a variety of substrates. However, flake soil is recommended for optimal growth
  • You MUST provide the larvae with a container that is at least 10 cm deep since they pupate vertically rather than horizontally. 32oz deli cups are perfect for them. 
  • Their care requirements are very similar to those of Trypoxylus dichotoma (Japanese rhinoceros beetles)
