Mecynorhina (Chelorrhina) polyphemus confluens Chapter 2

It’s been quite a while again since my last writing, but here are some new results of my Mecynorhina polyphemus confluens breeding:

Most of the larvae pupated around mid-January, meaning their whole larval cycle only took 6 months approx. (I received the parental adults in July 2014). I’ve never experienced this before for beetles of this size (I am confident to say that M. p. confluens is amongst one of those species that produces large sized beetles within a very fast larval cycle)!

Amongst the larvae that I had, 3 exceptional males already hatched, measuring resp. 68-69-70 mm in length exactly (max. L3 weights 35 g, 37 g and 40 g)! I would have loved to break the 70+ mm, but I still have 1 male that just pupated (max. weight recorded 42 g!) and the horn looks very promising!

Please enjoy the pictures! Growth curves and table will be posted soon!

The monster male in larva at 41 g of weight:

The monster male of 42 g max. larval weight in pupa (expected to be over 70 mm long):

The first hatched male of 63 mm (not that big, max. larval weight 33 g):

The bigger ones:


Male of 70 mm (max. larval weight 40 g):

Another male (69 mm, max. larval weight 35 g):

A male of 68 mm (max. larval weight 37 g):
