Anthropogenic change can alter the sensory information insects use to locate habitats, hosts, mates, refuges and seasonal environments. The ecological-trap problem arises not from attraction alone, but when a cue continues to guide selection after its relationship with habitat or resource quality has deteriorated. This ecological perspective separates cue response, behavioral selection, biological consequence and population inference. The distinction is necessary because many studies demonstrate strong responses to altered light, polarization, plants or substrates without simultaneously demonstrating that the selected option reduces survival, development or reproduction relative to available alternatives. Evidence from managed bumblebee colonies, invasive host plants, pesticide-contaminated hibernation substrates, restored aquatic habitats, artificial light and climate-shifted migration shows that cue–quality mismatches can occur through different mechanisms and at different life stages. Counterexamples show that anthropogenic habitat use can also be neutral or diagnostically incomplete. We therefore propose an evidence-bounded cue–quality mismatch classification in which ecological-trap inference strengthens only when attraction or selection and inferior biological consequences are independently demonstrated and appropriately linked. Population consequences require an additional scale-transfer step. This approach is intended to reduce false-positive trap diagnoses while retaining ecologically important disturbances that do not meet the stricter trap criterion.
