Actinopteri (ray-finned fishes) > Centrarchiformes
(Basses) > Centrarchidae
Etymology: Lepomis: Greek, lepis = scaled + Greek, poma = gill cover, operculum (Ref. 45335, 79012); humilis: humilis meaning humble, referring to the small size (Ref. 10294). More on author: Girard.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Temperate; 10°C - 28°C (Ref. 12468); 48°N - 29°N
North America: lower Great Lakes (in southern ends of Lakes Erie and Michigan), Hudson Bay, and Mississippi River basin from Ohio to southern North Dakota, and south to Louisiana in the USA; in Gulf Slope drainages from Mobile Bay in Alabama to Colorado River in Texas in the USA.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm TL male/unsexed; (Ref. 5723); common length : 7.4 cm TL male/unsexed; (Ref. 12193); max. reported age: 4 years (Ref. 72462)
Inhabits quiet pools of creeks and small to large, often turbid, rivers; usually near brush (Ref. 5723, 10294). Feeds on microcrustaceans and aquatic insect larvae, principally chironomid dipterans (Ref. 10294).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00610 - 0.02063), b=3.09 (2.93 - 3.25), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.55 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (23 of 100) .
