Habitat & Geographic Range

Clover Seed Weevil

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Found across Europe (4 countries) and North America (Canada, United States).

gray wolf

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, deserts and xeric shrublands, and tropical and subtropical dry broadleaf forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Seychelles), Asia (Japan), Europe (5 countries), North America (7 countries), Oceania and the Pacific (Marshall Islands, Vanuatu), and South America (5 countries). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Clover Seed Weevil

The clover seed weevil (Tychius picirostris) is a small weevil in the family Curculionidae, order Coleoptera, specializing in seed predation of clover species (Trifolium) and related legumes. Females oviposit directly into developing clover seed pods, and larvae feed within the seeds as they develop, consuming the cotyledons and reducing seed viability. A single larva typically destroys one seed per pod, and high infestation densities can eliminate a substantial proportion of seed yield in agricultural clover crops, making T. picirostris an economically significant pest. Adults feed on clover flowers and foliage before and after overwintering in soil and leaf litter, emerging in spring with host plant flowering. T. picirostris is distributed across temperate Europe and its range extends to North America including Canada and parts of the United States, where it has been introduced. In Europe it is recorded from countries including Denmark, Norway, Portugal, and Sweden. It inhabits meadows, grasslands, roadside verges, and agricultural clover fields wherever suitable Trifolium host plants flower. T. picirostris is classified as Least Concern on the IUCN Red List, with populations considered stable despite localized management actions by farmers seeking to reduce seed crop losses. Adults are two to three millimeters long, reddish-brown with a characteristic elongated snout, typical of curculionid weevils.

gray wolf

The most widely distributed wild canid, gray wolves range from North America across Eurasia in diverse habitats including tundra, forests, and grasslands. Highly social animals living in family packs led by a dominant breeding pair. As keystone predators, wolves regulate prey populations and profoundly shape ecosystem structure, as demonstrated by their reintroduction in Yellowstone. Once heavily persecuted, populations are recovering in many regions.
