Design for the Valley elderberry longhorn beetle

The Valley elderberry longhorn beetle (VELB) is endemic to California’s Central Valley, and a federally threatened species. VELB spend at least one year of life as larva boring through the stems of elderberry shrubs – their sole host plants. The habitat requirements of VELB are not fully understood, but they most frequently are found in riparian habitats, in larger elderberry shrubs and in clusters of shrubs. The elderberry shrubs can take on multiple growth forms depending on the physical site conditions as well as the neighboring plant community. In open woodlands, elderberry shrubs tend to grow as broad, dense shrubs with multiple stems, but in mixed riparian forests they grow taller and more like a tree. Both structures are used by VELB, therefore, habitats for VELB should be designed to incorporate multiple plant associations.
