Polyphylla decemlineata info

[a.ojala]

Hey I just went collecting yesterday and caught 12 Polyphylla decemlineata (10 lined June bug) larvae. They look pretty small so I assume there L1. I have a couple questions:

1) do the larvae need to consume plant roots, or are they fine with compost soil and decayed wood

2) how long does the larvae stage usually last for

3) what are adult life span

Thanks for the help

according to the information available at Washington State University, the larvae stage can last 2-4 years. They also have a lof of other information on the species found in the following link.

Thanks for the info. Wow 4 years, that's a really long larvae stage.

Has a 9-13 year long larvae stage. That's insane. that's almost as bad as cicada's.
