my Pachnoda are extremely prolific!
they share their 'tank' with the Peppered Roaches (Achrimandrita tesselata), a huge 3" roach of the Deadhead-roach-tribus; and they're outcompeting them in sheer numbers....
I gotta cull the beetle-herd pretty soon.
However, you need a large group to have a goodly supply of imago's or larvae as food for reptiles. few animals tackle adults (Pachnoda's stink!
, they're not yellow/black for nothing), but the L3 larvae (grubs) are good food.
you have to feed the grubs by hand (or pincet) to your reptiles though; they're really great diggers, and "sink" into any substrate with ease. only a true burying lizard (like some Scinc species or a Worm Lizard) can get at them, once they escape.
Too bad your wife vetoed the roaches! pound for pound roaches are THE best feeders for any insectivore. they're clean, they don't smell (most of them) and they're quiet.....
Maybe after you kept a Pachnoda colony she'll turn; because a healthy Pachnoda breeding tank stinks to high heaven
the male beetles fight over the females; the female beetles aren't always in the mood and any beetle flies into the sides of the tank or bumps the bulb. they're hardy and withstand it all, but.....they release their stinky fluid at ANY occasion
A blaberus colony is clean, doesn't stink, doesn't breed in the house, doesn't escape easily because they cannot fly or climb smooth walls or glass (unlike for example Gromphadorhina's; the wellknown Giant Madagaskar Hisser, wich is an escape artist).
I keep them like this:
I converted an old 35G tank to terrarium; just made a wooden hood with fine mesh for ventilation and added 2 60watt bulbs for heat and light.
there's a few branches for climbing and a rough terracotta saucer for food.
the substrate is about 4" thick and consists of:
-1/3 old leaves and bits of semi-rotted wood (no pine!)
-1/3 peat
-1/3 horse manure (!!)
adding dry catfood in the mix and some sepia for building up exoskeletons.
I feed lettuce, carrots, apples, oranges, melon, banana, curly kile, cucumber, strawberries, brambles, raspberries, grapes, tangerines, cantaloupe, pear, paprika, courgette; any other fruit or veggie I get my hands on; as well as brown bread, catfood, leftover fishfood, bits of old muesli, pie, cookies, leftover sandwiches, you name it
ANY veggie or fruit should be rinsed thoroughly...one bit of pesticide and ZIP no more bugs.
They eat EVERYTHING.......and once in a while I add a few bits of horsemanure. good thing I know a couple of guys with a horse!
I got more beetles than I can possibly feed!
I keep Eudicella's and Chlorocala's (Smaragdestes) exactly the same; except the Eudicella's share their cage with the PSG173 (stick insects), tanksize similar; and the Chlorocala's have a small 5G tank of their own.
I would rather breed one of these if you have a sensitive spouse; these two are just as easy as the Pachnoda, but they don't stink.....
