Rhino Beetle (Dynastes granti)
The following is a chart that I made to help identify
the Instar of a particular maggot.
|The following is information on the Width
of the Head for each Instar. This information
is based on two specimens.

They originate from Arizona, USA. Please note,
if you do not offer the larva Oak, Chestnut and
Birch (or just feed them one tree only), your beetles
will be much shorter then the ones in the wild.
Also, if not provided enaph difference in their
diet, the females will offen lay very few eggs,
or none at all. Their season in the wild occurs
from late July into October. They seem to live longer
if offered some watered-down maple syrup (not that
Larvas should be kept on a mixture of rotten wood,
dead leaves, and compost. Dynastes granti is the
longest Dynastid in the U.S. The thoracic horn is
very long on D. granti but is much shorter, in comparison,
on D. tityus males. The largest specimen ever found
measured 85mm long. After hatching, larvas usually
takes 6- 17 month to pupae. Some D. granti from
certain areas will not become adults till two years
after eggs are laid.
When breeding this specie, or any other Dynastes
species, for best results provide a fine soil, with
no sticks inside (keeping in mind to always have
some on top to ensure that in a case of them flipping
over, that they have to have something to grab onto
to go back up).
Females: get (4.4- 4.6 cm) long. They lay
as many as 50- 60 eggs, which usually take between
6- 8 months to hatch.
Males: get 3 1/2 inches (6.0- 8.5 cm) long.
Diet: Larva; Oak, Chestnut and Birch. Beetles; Apples, Bananas, etc. especially soft sugary foods.
