Mecynorrhina torquata ugandensis colour variations

Mecynorrhina torquata ugandensis is a big if not huge flower beetle. These beetles can grow over 80 mm, which is as big as a medium size goliath beetle. Geographically they can be found in  Uganda and DR Congo. In nature these beetles display a massive variety in their colours and patterns. Because of such variation, the dead specimen of the males of the species are very sought after by insect collectors, and some of them can be sold for as much as fifty pounds or even more (which mainly depends on the size and the rarity of colour variation/pattern of the specimen).  These species are great as pets, because they are quite easy: the adults are perfectly fine on ripe banana and their larvae can be easily raised on any decayed wood/leaf material.  Their cultivation led to appearance of some unusual forms such as "blue" colour variation, which I believe was "selected out" by Japanese breeders and now it is probably the most popular colour form present in culture.  In captivity, unless under certain conditions, the size of the males is normally within 50-65 mm, and the whole cycle from an egg to the adult at 25C can be completed as fast as in 8-10 months, which again makes them amazing pets, when the whole cycle of the beetle development can be observed within such short period.  I have been keeping a significant number of these beetles during recent years and despite the fact that their larvae consume a huge amount of the substrate during their development, they still are probably one of my favourite beetles. Here is a short slide show which I made from photos of my Mecynorrhina torquata ugandensis which I found on my flickr, phone and computer.

Goliathus orientalis preissi broken pupal cell and artificial puaption chamber

Just before constructing a pupal cell, a goliath beetle larva enters "the wondering phase". During this time the larva comes to the top of substrate "wondering" around, and trying to escape its current container. Such larva needs to be placed into a new box containing the mixture of peat and sand, where the larva will later construct its pupal cell. Sometime ago, I placed one of my golaithus orientalis larvae into such box and forgot to label it. Then later when I thought that the box had no larvae inside I decided to use it for another wandering larva goliath beetle larvae. The result was not very nice, as the first larvae finished its cell already and I accidentally broke it while preparing the substrate in the box for the larva N2.  The larva inside of the cell was still pretty active, and I was hoping that it will have some energy to repair the cell, although the damage was massive:(.  Normally such cell damage in large flower beetles such as Mecynorrhina results in larva leaving the cell and dying eventually, as it would not have enough to build a new pupal cell. I left the larvae in the broken cell as it is, and luckily one month later I discovered that it did not leave the cell. I transferred the larvae into the artificial pupal cell made from floral foam and about 2 days ago I discovered that it turned into a gorgeous female pupa! Please see the photos below.
