ANIMAL ESTATE client 5.7: SNAIL-EATING GROUND BEETLE

FOR ANIMAL ESTATE 5.0: PORTLAND

SCIENTIFIC NAME: Scaphinotus angulatus

RANGE: British Columbia, Washington, Northwest Oregon.

HABITAT: Common in forests, parks, and gardens.

HOME CONSTRUCTION: To attract these flightless beetles, it is advantageous to leave part of a yard in a semi-natural state, perhaps with downed logs or a patch of shrubs.   Mosses are a welcome presence, as in woodlands, mosses provide a hiding place for Scaphinotus.   They also scurry around under leaf litter and bark pieces.

BUILDING MATERIALS: Downed logs, leaf piles, bark pieces.

BUILDING MOTIVATION: Ground beetles feed on snails, and sometimes slugs - who to many gardener's dismay, feed on the plants of a typical garden.

THREATS: Forest clearing and non-native pests.

INTERESTING FACTS: Scaphinotus' narrow, elongated head has helped the beetle adapt to its diet of snails.   The beetle inserts its head inside the aperture of the coiled snail shell and proceeds to eat.
