While attempting to identify the eggs and nympths I came across some guides:
- Field Guide to Stink Bugs of Agricultural Importance in the Upper Southern Region and Mid-Atlantic States (PDF)
- Orkin Insect Identification Guide (PDF)
- Good Bug? Bad Bug? An identification guide for pest and beneficial insects in summer pulses, soybeans, peanuts and chickpeas (PDF)
- Beneficial Insects - The Back Pocket Guide (PDF)
