|SHB larva Top - Wax Moth Below|
Here is what I suggest you look for:
- Spines - Only the SHB has them.
- Beetle like head - Wax moth does not have this.
- Many many larva - Wax moths usually only number a few per frame at most times.
- Silk - SHBs do not spin silk.
- Visible SHB adults present
- Last compare the photo to your suspect.
