oviposition

[Mark]

I do have a question my Beetles (pachnoda ephippiata) are not producing any eggs.

is that common for more beetles ?

I did put in substate of other larva and beetles how are laying eggs, as write in orin book

I also put them near the window for some natural light

Are there more things that I can do and not yet think about?

Greetings Mark

Pachnoda are known to like deep substrate. Keep trying and adding substrate components, once they get started there will be tons. It's strange Pachnoda are so dirt common in Europe yet many people have trouble getting them to lay eggs.
