Hello all, Today I got this small Goliathus specimen, I thought just to be a small G. orientalis. But when I put it the cabinet next to my other Goliath beetles, it occured to me that the black markings on this little fellow's elytra are actually quite red(/brown). The marking color highly resembles the brownish-red color on my G. Goliathus specimens, while the markings are clearly orientalis-like. In my other orientalis specimens the markings are just black, no trace of red to find in there. (I included some pictures that show them next to each other.) This makes me wonder if this 'red male' just happens to be a little more red than my other orientalis specimens, or if it's actually a diffent color morph. (Or maybe even a goliathus morph?) Chances are high, it is just a reddish G. orientalis but I'm wondering so I hope someone can make it clear to me. Thanks in advance! P.s. I know these beetles aren't well-set, but this is the way I got them and I will fix it later.

Hello
I would say it's just a bit more reddish orientalis. I supose that the strenght of the reddish or black color on the elytra depends on the thickness of the elytra itself rather than any other factor, so it's just maybe a development feature of the specimen or population.
Regards

looks like orientalis to me. Suttle color variation is often not a reliable character when identifying specimens. Factors affecting color are many including; (as stated above) population variations, living and dead age of specimens, specimens killed just after pupating will be light in color, specimen killed imediately after metamorphosis, grease content- as fats are often released once the specimen dies releasing fats and causing discoloration and ofcourse natural color forms and seasonal variants.
Nice specimen by the way it looks very fresh!

That's what I thought. I just wasn't sure. There are indeed lots of factors contributing to a specimens' appearance, but the bright red color threw me of guard. It looks quite nice for a specimen that is over 50 years old and the reddish color brings something different to the cabinet. It's a keeper Thanks for the response guys!
