Delphacodes scolochloa
Cronin & Wilson, 2007
Delphacodes scolochloa is a wing-dimorphic planthopper described in 2007, inhabiting prairie pothole wetlands of the North American Great Plains. The species exhibits two distinct wing morphs: brachypterous (short-winged) and (long-winged) individuals, with significantly different capabilities. Research has focused on its movement , patterns, and establishment success in fragmented wetland , revealing strong Allee effects on establishment.

Identification
Distinguished from other Delphacodes by wing dimorphism with brachypterous and forms co-occurring in . Brachypters have reduced wings limiting capability, while macropters possess fully developed wings enabling longer . Specific diagnostic morphological features for species-level identification require examination of genitalia and detailed morphometric analysis; consult original description (Cronin & Wilson, 2007) for definitive characters.
Habitat
Prairie pothole wetlands of the North American Great Plains; specifically associated with temporary and seasonal wetland created by glacial activity. Occupies emergent vegetation patches within these depressional wetlands.
Distribution
Recorded from North Dakota, North America. Distribution appears restricted to the prairie pothole region of the northern Great Plains, though precise range limits require further survey.
Diet
Phloem-feeding on plants within prairie pothole wetlands; specific host plant not documented in available sources.
Behavior
Movement patterns follow a simple diffusion model. individuals disperse approximately three times farther than brachypters (mean 8.1 m vs. 2.8 m per day among patches). Brachypters are -limited at less than 38 m. of vacant patches increases with patch size for both morphs; brachypters additionally show decreased colonization with increasing isolation distance. Establishment success is strongly influenced by size, with Allee effects constraining new formation.
Ecological Role
Herbivore in prairie pothole wetland ; serves as for ( not specified). and spatial structure influenced by fragmentation and limitation.

Wing dimorphism and dispersal ecology
The represents a model system for studying in fragmented landscapes. The coexistence of brachypterous and morphs represents a trade-off between dispersal capability and reproductive investment, with macropters sacrificing for ability.
Research significance
Studies of D. scolochloa have contributed to understanding how movement up to influence spatial structure and spread in heterogeneous environments. The demonstration of Allee effects on establishment success has implications for understanding dynamics in fragmented .
