Introduction

Phyllophaga Is a genus of beetle commonly known as may beetles. Many of the beetles in this genus need to be dissected to identify to species. Both male and female specimens are useful for identification. This post will eventually be a guide to the Phyllophaga species found in Vermont. As I find more species I will add more images and species to this list.

• Phyllophaga anxia
• Phyllophaga fusca
• Phyllophaga hirticula

Introduction

There are two species of invasive June beetles in the tribe Sericini in Vermont; Nipponoserica peregrina, and Maladera formosae. They can be distinguished from each other and native species using external morphology but this guide also includes identification using the genitalia. Both species are common in Vermont.

Species list

• Nipponoserica peregrina
• Maladera formosae

Identification

Nipponoserica peregrina male.



Maladera formosae male.

Identification through external morphology

Maladera formosae

Maladera formosae can be separated from Nipponoserica peregrina by It's rounder and darker brown appearance. The genitalia are very distinct between these two species. It is also resembles the native genus Serica but can be separated through dissection or by a few small features described here at bugguide.net.

Nipponoserica peregrina
