Identifying Aphid-Like Insects on Potato Plants in Florida

A gardener in Florida (zone 9) observed fire ants tending to small, elongated green insects with two black spots (one near head, one near tail) on potato plants. The insects appeared to be feeding on plant sap.

Likely Identity

Jack DeAngelis notes many insects fit this description. The fire ants were likely harvesting honeydew excreted by sap-feeding insects such as aphids, scale crawlers, or psyllids. Without a photo, precise ID is impossible.

Next Steps

• Take clear photos (close-ups of insects and plant damage).
• Collect a few specimens in alcohol and bring to the local county Cooperative Extension office. Master Gardeners can provide accurate identification and region-specific management advice.
• Search "Master Gardener + [your county] + Florida" for contact info.

Accurate ID ensures targeted, effective control—especially important for edible crops.
