【4 Artificial Pupation Chambers for Hercules Beetles】 *Images 7-9 are examples of use, not for sale.

Thank you for viewing.
This is a set of 4 artificial pupation chambers for Hercules beetles.

I have hollowed out new unused water-retaining sponges (Oasis) and placed them in new cases.

As these are handmade by an amateur, there may be slight differences in depth and width, even if they appear similar.
You can easily make adjustments to the product you receive.
After that, you can easily deepen or widen the chamber by simply rubbing it with your hands.
The dimensions of the processed Oasis are approximately:
Length: 21.5 cm, Width: 10.5 cm, Height: 7.5 cm.

Regardless, these are handmade by an amateur, so please only purchase if you understand this.

For reference, photos 7, 8, and 9 show current examples from February of this year, with pre-pupae, pupae, and newly emerged adults.
Although I managed the pupation chambers more roughly than the ones for sale, both males and females are progressing smoothly in the artificial pupation chambers towards emergence.
This is for your reference.

Thank you.
