Phalacrognathus muelleri - Rainbow stag beetles - Adult trio

Rainbow stag beetles - These beetles have been captive bred in the UK.
 
The adult beetles are feeding well on ripe fruits and beetle jelly. Adult pairs should be given plenty of space with an enclosure that can provide a substrate depth of 8-10 inches minimum. This will allow females to get away from males and bury to lay their eggs. Females will lay in decayed oak/beech mulch, Flake soil or rotton logs. 
Temperature of 23- 27 degrees C is the ideal range but they will tolerate some minor fluctuations.
Humidity - soil should be damp but not soaking wet and a light spray daily - every other day depending on the time of year.
