Scientific Name: Lasioglossum lustrans (Cockerell, 1897)

Common Name: Carolina Desert Chicory Sweat Bee


Panurgus lustrans Cockerell, 1897a: 147 [♀]

     Syntypes ♀. USA, New Mexico, Lincoln Co., Lone Mountain, near Silver Springs, “Mr. Clark Rodger’s ranch”, 7 July 1896, on Pyrrhopappus [CAS]


Species Notes

The ♂ was described by Mitchell (1960). Cockerell (1897b) later proposed the genus Hemihalictus (now considered a subgenus of Lasioglossum) for this species due to it normally having two-submarginal cells in the forewing (but see Gibbs 2010). As a result of more recent analysis (Gibbs et al. 2013) the name Hemihalictus is applied in a much broader sense (Gibbs et al. 2013).

The DNA Barcode Index Number (BIN) for this species isBOLD:AAD7652.



♀ body length: 5.9–6.9 mm; head length 1.82–2.03 mm; head width: 1.85–2.08 mm; forewing length: 4.5–5.3 mm

♂ body length: 5.0–5.9 mm; head length 1.35–1.50 mm; head width 1.40–1.55 mm; wing length: 4.5–5.0 mm



Though this species is considered oligolectic on Pyrrhopappus carolinianus (Asteraceae: Cichoriae) (Michener 1947; Daly 1961), its northern range, including its presence in Canada, exceeds that of this plant (Estes and Thorp 1975). Thus, L. lustrans  is capable of obtaining pollen from other plant species. Arduser (2010) and Grundel et al. (2011) report L. lustrans foraging on Krigia biflora and K. virginica (also Cichoriae, Asteraceae). Lasioglossum lustrans has also been collected from Pyrrhopappus pauciflorusCichorium intybusHieracium gronovii, and Cucurbita (Cucurbitaceae) (Michener 1947; Mitchell 1960; Moure & Hurd 1987; Grundel et al. 2011).

The nesting biology in Louisiana was studied by Daly (1961). All nests studied were occupied by a single female and was established in bare ground with a vertical, unbranched main tunnel that reached a depth of up to 29 cm. Natal cells were built at a slight downward angle at the end of 1.5 cm long lateroids, but no nests contained more than four fresh cells. Some females may reuse nests as some contained upwards of ten old cells (Daly 1961).
