Darkling Beetles Splitting?

post #1 of 9
Thread Starter 

I started my mealworm colony about a month ago and have about a dozen beetles (that I can see).  I noticed yesterday that one of them is split along the entire length of the back.  Is this normal and why did it do that?  I haven't read anything about them splitting like this.

I currently have a very empty nest...  Is this what growing old, alone will feel like?

It's not split. You're seeing the elytra (hard wing covers).  Each elytron covers one wing on one side of the body.  They sometimes spread apart shortly after pupating.  It's all completely normal.

Awesome information.  Thanks.  I'll have to look that up, but it makes me feel better.  I was a bit worried.

My beetles appear to be struggling. I'm new at this. I find them on their backs with their legs waving around and a few have died. Is the substrate too fine? I put in some whole wheat flour mixed with non-medicated chicken crumbles and oatmeal

Do you have a picture of your setup?

 I have had problem with a recent batch of darkling beetles wing covers not developing?  so far they are mostly all alive,  the only thing I did differently is instead of the bedding rolled oats I used whole oats, anyone have a similar issue or any ideas?

What are you feeding them?

 

They need fruit/vegetable/etc. for moisture and nutrition. If you don't feed them for a long time, they will cannibalize each other and their young won't develop properly.

Thanks HeritageGoose13, that's it exactly. I have never had that problem because twice a day I check pupa container for beetles and transfer, but I think this happened with a bunch when I left for 24hrs. I had been separating out pupa and putting no food or moisture in that container and have had zero issues until this. This site is great!
