I have had luck w/ tityus.
i keep mine in gallon pickle jars w/ 50/50 mixture of compost manure and top soil.
place male and female together for a couple days,they should breed
separate them
leave female alone for a month or so and wait
within a month or so u should have eggs
eggs take a month or so to hatch
if your going to keep grubs you must collect decaying wood and some leaves; the grubs do eat dried dog food as well
bake the wood and leaves at 250 for 3 hours to kill wire worms etc mix
Adults do well on apple slices soaked in diluted syrup
add couple hand fulls of wood as needed and dog food too its supposed to make for bigger beetles!!
i had to sift thru the soil to find the eggs and the grubs are tiny like pencil eraser-size it takes a year to transform into adults
get the rearing of dynastes granti book and u should be fine
Good Luck!
