Mecynorhina torquata ugandensis breeding 2015-2016 - more emerging adults

Hello,

This year, the breeding of Mecynorhina torquata ugandensis was very satisfactory. I have had larvae that weighed up to 55-56 g right before pupation and average full L3 weights up to 46 g.

Most of the MTU adults became 70+ mm large males or 55+ mm females with even some exceptional individuals. My largest female this year ended up measuring 61 mm and a male reached 76/77 mm. Most other males ended up at 73-74 mm.

These results can be seemingly achieved by lowering the temperature range to 18-21°C instead of the classic 20-25°C (mostly recommended as typical rearing temperature of the larvae), next to the fact of always providing the larvae with optimal substrate (50% wood and 50% leaf humus). The larvae will grow slower and sometimes take up to 1,5-2 years; however, the weight each larva reaches will be significantly higher than the ones reared above 22°C

Currently, I am trying to further improve my breeding by adding some protein additives to the substrate. Apparently, dried Gammarus shrimp, dried pellets for kitten, koi carp pellets and/or dried dog pellets seem to work fine. I am using dried dog pellets (Bakers Complete Meaty Meals) and dried Gammarus shrimp. This might give a good protein boost to the larvae, but I am also convinced that a separate breeding of the L3 larvae might give an even bigger growth; this would then be the next challenge. For now, I am trying the additives (these worked very well for my M. polyphemus confluens breeding this year).
