Scientific Name: Hoplitis sambuci Titus, 1904

Common Name: Elderberry Small-Mason


Hoplitis sambuci Titus, 1904: 101 [♀, ♂].

     Holotype ♀. USA, Washington, Pullman, 7 May 1895, by C.V. Piper, reared from stems of Sambucus glauca [USNM no. 6860].


DNA Barcode Index Number (BIN): BOLD:AAE4979

Biology: Titus (1904: 101) reared this species from stems of Sambucus glauca; Linsley and MacSwain (1943: 597) reported it as a host of Trichodes ornatus Linsley and MacSwain, 1943 (Coleoptera: Cleridae); Michener (1947) also reared this species from pithy stems. The nesting biology was described by Clement and Rust (1976) and Frolich et al. (1988). It will accept hollowed or drilled stems 4.5-6 mm in diameter and produce up to ten cells per nest (Clement and Rust 1976). Nest plugs consist of two layers of masticated plant material and small pebbles and/or wood chips (Clement and Rust 1976).

Distribution in Canada: Michener 1947 [BC]; Buckell 1950 [BC]; Hurd and Michener 1955 [BC]; Elwell 2012 [BC]; Rowe 2017 [BC]; Sheffield and Heron 2019 [BC].
