The Discussion

Posts: 34Beetles can be very tricky to identify. It has been my experience that it is extremely difficult to identify many insects to the species level based on pictures alone. It may not be able to be positively identified to genus either. The family is probably correct though, except the family isn't listed here. The family should be Hydrophilidae. Hydrophiloidea is a superfamily designation. Having said that, GONZO's ID could be correct (and if he has the experience, probably is), it's just not possible for me to confirm this.
