Hi all,

I started a new breeding of Dynastes hercules occidentalis around 12/2012 - 01/2013 (I obtained F1 larvae by crossing my two breeding lines).

The current results are striking! Only around 1 year after the hatching of the eggs, most of the male larvae have crossed the 100 g bar! One male L3 even weighs 107 g!!!







Maybe this time I can reach 110+ g? There are 8 male L3 larvae in breed. I will post a growing graph upon the next substrate change (around Christmas).

Kind regards,
Tom

Amazing weights! What substrate do you use?

LOL Thanks Matt! :wink:

I have been using simply classic Dynastid substrate, mainly composed of finely shredded white/light brownish-rotten oak wood (a little beech in it as well) on the bottom of the containers (approx 40-50%) and topped by oak/beech leaf humus. Substrate change was done every 1,5-2 months.

Kind regards,
Tom

I am really hoping that they'd grow just a little more... The last weighing was on the 15th of October and until now I haven't seen any signs of prepupation; the larvae just remain on the bottom of their buckets and I assume they continued feeding, so I expect them to reach/pass 110 g (at least one larva should).

About 1,5 years ago, I had two very nice males:

L3 max. weight 103 g = 132 mm adult male
L3 max. weight 107 g = 133 mm adult male

Is it better to keep the wood separated from the leaf mulch for Dynastes?

also, beautiful photos but were you not worried that they would take off and fly away?

Thanks for the comments everyone! :wink:

I always keep a quantity of the shredded wood separated and I add 8-10 cm of this on the bottom of each container (where the larvae mainly reside during their feeding). There is also a smaller part of it mixed with the leaf humus substrate, but from what I have experienced: the larvae mainly feed on the wood (some Dynastes hercules ssp. like lichyi will rather eat leaf humus as well, but most of them eat more wood than leaf humus during their growth).

The adults on the tree were still in diapause although they already showed their definitive colours. I would've never taken them out while being active. :wink:

Just a little update from this breeding. Most of the males are in prepupation stage, one male (final weight 104 g) has already successfully pupated.

A little overview:




Some final weights (25/12/2014):





The one L3 (final weight 104 g) in prepupation:


After 2,5-3 weeks:





I measured it at 155+ mm, so I hope to have a 135+ mm male.

More news will soon follow!

Some photos of my latest breeding results from Dynastes hercules occidentalis:


Male 138 mm (max. L3 weight 104 g)



4 males together (138 mm - 104 g L3, 136 mm - 113 g L3, 128 mm - 94 g L3, 116 mm - 104 g L3)

To be continued...

Dear Bahamut and everyone.

I want to buy and breed a Dynastes hercules occidentalis.
Where could I get one please?. I live in Bristol (UK) and I need to make a film about this species that lives in the Colombian Chocho.

Anyone out there that would have one or could tell me how could I get one?.

Thanks so much!

Angel
