Leaf insect eggs

[Rhino1]

I've been incubating these eggs from Extatosoma and phyllium sp, I seperated them into lots of 100 per tub and everything seems to be going well, they actually look like they've become bigger/swollen in the past month or so, some look to be slightly elongated also.
I know they can take forever to hatch and they are at around the 4 month mark now, they look good, nice and glossy no mould etc.
My question is would anyone have some tricks of the trade to help things along, speed the process up maybe?

I've never noticed extatosoma eggs changing size before...but if they look clean and glossy and the change isn't caused by mold growth inside the egg pushing on the cap I guess nothing's wrong.

I can't speak for Phyllium, but Extatosoma eggs are some of the toughest insect eggs out there. You can leave them in a plastic bag with no moisture for 7 months and they'll still hatch when exposed to better conditions. The way to speed up the hatching process is to keep them in warm and humid conditions, but excess warmth and humidity is also the most effective way to kill them via mold. So keep them with good ventilation and let them dry out a little on occasion to deal with microbial growth. The minimum time it can take for them to hatch is around 3-4 months.

I've raised Phyllium before, in well ventilated containers, under a layer of thin gauze/ padding paper, to avoid direct water contact while misting, once ev. couple of days. I like to keep fresh leaves that I keep refreshing though, but thats not necessary. It took for us effectively 4-5 months for the eggs to hatch, and most incubation was in winter, where I held Temperatures arond 25-28 degs celsius, so the females got to live to see their offspring. Probably T. is a playing factor on speed to hatch, but I can't vouch for that.
Good luck, they are nice little fellas.
