Habitat prefernce for the aestivation of Hyper postica was researched by the sampling of field borders. Sampling methods by the sampling of field borders. Sampling methods included soil and vegetative litter collection, sweeping of borders with an insect net and emergence trapping of wooded and grass habitat. Fields were swept once a week to determine if H. postica returned to the field before the winter season. The methods resulted in the following findings: Weevils do not aestivate litter. Data from sweeping indicated that weevils prefer areas that include alfalfa and grasses. Results of observations implied that there is a direct relationship between population density of weevils and density of vegetation if the vegetation includes alfalfa and grasses. Emergence traps support the data that shows weevils select sites that include alfalfa and grasses. Field sweepings indicated that weevils began to return to the field in late August.
