Telling them apart
Bluegill vs Pumpkinseed Sunfish
Look at the ear flap. A bluegill's is solid black with no coloured edge or spot. A pumpkinseed carries a bright orange-red spot on its trailing edge, and has wavy blue-green lines across the cheek that a bluegill lacks entirely.

Why the difference matters
Most states manage them together under a combined panfish limit, so this is rarely a legal question — it is a question of knowing your water. The two frequently share the same bank, and where pumpkinseed dominate you are usually on cooler, clearer, weedier water than a bluegill-heavy pond. It is also the identification children ask about most, and the ear flap settles it in a second.
Size limits, bag limits, slot limits and seasons are set by your state wildlife agency — and for many offshore and migratory species by federal regulators — and on many waters they differ from the statewide rule. They also change between seasons. Check the current regulations for the exact water you are fishing before you keep a fish — we do not republish limits here, because a number that is a season out of date is worse than no number.
