Macropterous

Definition

Having fully developed, functional wings of normal or elongated size; contrasted with brachypterous (short-winged) or apterous (wingless) conditions. In insects, macropterous morphs typically possess wings reaching or exceeding the abdomen tip and are capable of flight, often representing the dispersal phase in species with wing dimorphism.

Etymology

From Greek makros (large, long) + pteron (wing)

Example

In the leafhopper Aconurella montana, the macropterous variety possesses elongated wings enabling long-distance dispersal, while brachypterous individuals are flightless and remain near the natal host plants.

Synonyms

• long-winged

Related Terms

• brachypterous
• Apterous
• Micropterous
• wing dimorphism
• dispersal polymorphism
• Alate

Usage Notes

Used comparatively within species or higher taxa to distinguish fully winged from reduced-wing morphs. Some authors restrict 'macropterous' to wings distinctly longer than the body, using 'brachypterous' for moderately reduced wings and 'micropterous' for vestigial wings. In aphids and other Hemiptera, macropterous forms are often seasonally induced and associated with host switching or migration. Not all long-winged insects are termed macropterous—usage is most common in groups with documented wing polymorphism (Hemiptera, Orthoptera, Coleoptera).
