Eupatorus gracilicornis

A shame that it's stuffed. I didn't knew this beautiful species.

It's not stuffed but dried
Arachnids, female moths and orthoptera usually require stuffing, to preserve the volume of abdomen. Most beetles are sturdy enough to retain their body shape.
E. gracilicornis is one of the cheapest rhino beetles for collectors, if purchased dried.

Well, I meant dried. I knew that hard-exoskeleton arthropods such as beetles are not a taxidermy work like mammals and birds. I collected and prepared myself a not small insect collection during many years.
Ah, and othoptera are not very deformed with the drying, only the most "fat" ones (like Ephippiger and allies). Many "soft" arthropods are better kept in alcohol or formol, the most "deformable" ones according to my experiencie are the bronze bristetails (Machilidae).

The prices are lowest possible, and at other sites the insects are being overpriced.
All species sold here are not protected, and many are being farmed (such as large butterflies).
Most beetles are harvested though.

I better not told this - almost all Macrodontia cervicornis got sold out overnight
