Take this somewhere

This page is the record. The reading is what happens when you add water, a season and a temperature to it — that is where the families below get ranked against each other instead of just listed.

The half nobody publishes

What this record does not know

Everything else on this page comes from a named agency or peer-reviewed source. This is the other side of that: the questions a reviewer went looking for an answer to and came back without, and the fields the record leaves empty because filling them would mean guessing.

It is here rather than at the bottom because a page that only shows what it knows is easy to read as a page that knows everything. For Longear sunfish there are 11 of them.

Absent from the record

2

No reviewer wrote a gap here. The field is simply empty, which is its own answer.

Water temperature

No agency or peer-reviewed temperature band for Longear sunfish was found that a review would accept. The reading runs without one rather than borrowing a number from a related fish.

Population context

No regional population profile is registered. The species-level reading stands on its own; it does not silently become a local one.

Where the record puts it

Water and range

Central and eastern North America, especially clear rocky/sandy streams and connected impoundments of the interior.

Flowing water

5 reviewed holding classes
  • Eddy
  • Side channel
  • Current break
  • Pool tail
  • Submerged wood

Stillwater

5 reviewed holding classes
  • Weed edge
  • Shallow flat
  • Rocky shoreline
  • Wood
  • Inlet

DepthPrimarily shallow-to-mid littoral/pool fish around rock, sand, vegetation, and current relief.

Moving waterStream-oriented but avoids strong current; favors pools, inlets, overflow water, and protected edges adjacent to moving water.

LightStrongly daytime-active sight feeder; clear water and structure support visual insect/crustacean feeding.

Thermal band

Temperature

No reviewed temperature band

Nobody publishes a preferred or active temperature range for Longear sunfish that a review would accept. Borrowing one from a related fish would look like knowledge and behave like a guess, so the reading runs without it and says which parts of the answer that weakens.

How it uses water

Behaviour

Missouri DNR: nests in colonies, often so close that rims nearly touch. Colonial nests are never a targeting recommendation. Catalog exception: more stream-associated than bluegill but still avoids the fastest current core.

Missouri DNR: carnivorous, feeding on insects, small crustaceans, and some small fish. Illinois DNR: follows turtles and suckers as they feed on the bottom, eating organisms dislodged from the substrate. That is a feeding mechanic, not a current event and not a recommendation to work nesting colonies of other sunfish.

Missouri DNR: most active in daytime. Clear water and structure support visual insect and crustacean feeding.

Seasonal activityMissouri DNR: nests in colonies from mid-May to early or mid-August. Illinois DNR: spawns May through August. Conservation context. Summer remains a clear-stream pool problem.

Temperature-driven behaviourPreferred band roughly 68–80°F. Cold edge near 50°F; warm edge near 90°F. Clear permanent-flow water is the default, not a weedy bluegill pond.

Depth movementPrimarily shallow-to-mid littoral and pool water around rock, sand, vegetation, and current relief.

Facing the currentMissouri DNR: avoids strong currents. Occurs in reservoirs, ponds, and in pools, inlets, and overflow waters adjacent to stream channels. Favors clear, permanent-flowing streams with sandy or rocky bottoms and aquatic vegetation.

CoverEddy, side channel, current break, pool tail, submerged wood, weed edge, shallow flat, rocky shoreline, and inlets.

Open waterNot a pelagic schooler.

Predator avoidancePools, vegetation, and current relief. The fastest open lane is a poor default.

TerritoryPools, inlets, and protected edges. Nesting males remain with the nest for more than two weeks (Missouri DNR).

Spawning (conservation context)Missouri DNR: evenly rounded nests nearly always fanned over small chert gravel; rims often nearly touch; the male stays with the nest for more than two weeks until fry have hatched and dispersed. Colonies are excluded from target guidance.

Where the general rule stops

  • Longear sunfish are more stream-associated than bluegill but still avoid the fastest current core.
  • Spawning males can be unusually visible and territorial; nest visibility is not a recommendation to target colonies.

What it can eat

Forage

A capacity list, not a report from this week. What is actually available on your water is a separate question, and Hatch Match is the tool that asks it.
  • Aquatic insects
  • Terrestrial insects
  • Crustaceans
  • Small forage fish

Missouri DNR: insects, small crustaceans, and some small fish. Illinois DNR: insects, fishes, and crayfish. Mollusks are not a catalog class on this record — do not import a pumpkinseed or redear snail diet. Capacity is not a current hatch.

Feeding style
Opportunistic
Feeding zone
Mixed

Through the year

Winter
Remaining insects and crustaceans in deeper pools.
Spring
Aquatic insects and crustaceans as water warms.
Summer
Insects, terrestrials, crayfish, and some small forage fish in clear stream pools. Surface foods are capacity when observed.
Late summer
Insects and remaining terrestrials along pool edges. Nesting overlap may continue; that is conservation context.
Fall
Insects and remaining small fish along cover.

By life stage

Young of year
Small aquatic insects and crustaceans.
Juvenile
Insects and small crustaceans.
Adult
Insects, terrestrials, crayfish-scale crustaceans, and some small forage fish.

Ontogenetic shiftSmall invertebrates to mixed insect–crustacean, with small fish where gape allows.

SubstitutionsClear rocky streams substitute crayfish and insects. Do not import a mollusk specialist diet this record does not have.

Diet capacity is not proof that a hatch or prey event is occurring. Observed current forage still comes from a user observation or Hatch Match.

Through the year

Season

Longear calendars are clear-stream pool calendars. They are more stream-associated than bluegill but still avoid the fastest current core. Colonial nests from mid-May into August are conservation context. They are not redbreast.

Winter

Where they sit
Deeper pools and remaining current relief in the usable band.
Feeding
Slow intercept of remaining insects and crustaceans.

What that changesDrop presentation, slow drag, and live / natural bait suspension. Flowing water: dead drift and stationary bait.

Early summer

Where they sit
Clear stream pools, inlets, overflow water, and vegetated rocky or sandy margins.

What that changesDrop presentation, pulse / jig, and dead drift in slack.

What would count against it

  • using nesting colonies as holding water

Missouri DNR: nests in colonies from mid-May to early or mid-August; rims often nearly touch. Colonies are excluded from target guidance.

Summer

Where they sit
Pools, inlets, overflow water, weed edges, and rocky shoreline adjacent to moving water.
Temperature
Preferred 68–80°F. Missouri DNR: most active in daytime. Avoids strong currents.
Light
Clear water increases visual feeding and shade use at high sun.

What that changesDrop presentation and slow drag. Surface retrieve only when terrestrials are observed. Flowing water: dead drift, pulse / jig, and stationary bait.

What would count against it

  • collapsing longear into redbreast
  • forcing a still-water bluegill pond default

Late summer

Where they sit
Pools and vegetated edges. Nesting overlap may continue into August.

What that changesDrop presentation, slow drag, and live / natural bait suspension.

Missouri DNR: male remains with the nest for more than two weeks. Nesting remains caution.

Fall

Where they sit
Pools, inlets, and remaining wood as water cools.

What that changesDrop presentation, slow drag, and dead drift.

Spawning · Early summer, Summer, Late summer

Colonial nesting can extend from mid-May into August. Nest colonies are conservation/ethics context, not a targeting recommendation.

Recorded as conservation context. No spawning site, staging concentration or migration bottleneck is named anywhere in this catalog, because naming one is how a population gets fished out.

Telling it apart

Identification

Blue-green sides speckled with yellow and emerald, orange or yellow belly, and a sky-blue maze on the cheek. Color intensifies on nesting males and is not the only key.

What to look at

  • Missouri DNR: the ear (gill) flap is elongated, black, and often bordered in white. Illinois DNR: the black flap on the gill cover is very long and white-edged.
  • Missouri DNR / Illinois DNR: pectoral fin is rounded and short — not the long pointed bluegill or pumpkinseed pectoral.
  • Missouri DNR: side of the head olive or light orange with sky-blue vermiculations (undulating, worm-like markings).
  • Back and sides blue-green speckled with yellow and emerald; belly yellow or orange (Missouri DNR). Breeding males show a bright red-orange belly (Illinois DNR).
  • The long flap is the namesake mark, but the white edge plus short rounded pectorals split this fish from redbreast, whose flap is entirely black.
Average adult length
Missouri DNR: total length commonly 5–6 in. Illinois DNR: typically about 6–7 in.
Common angling size
4–7 in in clear rocky or sandy streams and connected pools.
Typical weight
Missouri DNR: maximum about 7 in and 4.5 oz in that account. Typical fish are lighter.
Maximum documented
Large longear exceed the 5–7 in band in some waters but remain smaller than trophy bluegill or redear. Maxima are waterbody-specific.
Longevity
Missouri DNR: individuals can live for 6 years.

What it gets confused with

Redbreast sunfish
Redbreast flaps are entirely black and no wider than the eye; the body is more elongated. Longear flaps are often white-edged; pectorals are short and rounded; the body is deep and slab-sided.
Pumpkinseed
Pumpkinseed have a short flap with a discrete red-orange spot and a white margin, plus long pectorals. Longear have a much longer, often white-edged flap and short rounded pectorals.
Bluegill
Bluegill have a short plain black flap, a soft-dorsal spot, and long pointed pectorals. Longear have a very long white-edged flap and rounded pectorals.
Green sunfish
Green sunfish have a large mouth and an elongated body. Longear mouths are moderate; the body is deep and slab-sided.
