To determine whether habitat quality and spatial isolation act as competing or complementary drivers of insect population persistence in fragmented landscapes.
Quantified microhabitat requirements, niche variation, and carrying capacity for three butterfly species: Melitaea cinxia, Polyommatus bellargus, and Thymelicus acteon.
Surveyed population distribution, density, patch size, habitat quality, and geographic isolation across all potential habitat patches in three UK landscapes.
Within-site habitat quality explained patch occupancy two to three times better than site isolation across all three butterfly species.
Habitat patch area showed no correlation with species occupancy in any of the evaluated populations.
Habitat quality and spatial isolation operate hierarchically rather than as alternative mechanisms, identifying habitat quality as a primary parameter in metapopulation persistence.

Implication

Ecological survey demonstrates that habitat quality and isolation jointly determine butterfly persistence, indicating habitat condition is crucial for metapopulation conservation.
