Andrena salicifloris
miner bee species in the family Andrenidae
Andrena salicifloris, or the willow flower miner bee, is a miner bee in the genus Andrena. Another common name for this species is the willow mining bee. The bee ranges from Colorado to California and north to British Columbia, and often inhabits arid and alpine lands. The bee is often black or dark brown, and is sparsely coated with grayish hair on the thorax, legs and on the abdomen. The pollen basket is on most of the hind leg. The wings of the willow flower miner bee are smoky, and their veins are black.
As in the case of most bees, adult willow flower miner bees drink nectar, whereas the larvae feed both on nectar and pollen. The nests of the willow flower miner bees are created when a mated female bee excavates a small tunnel that branch off into small branches. These branches each contain a brood cell, and once each cell has pollen and nectar for the larva to feed on - a small doorway to the brood cell is closed. The larva grows rapidly, but the bees do not emerge until spring.
Begin with the source’s own compact description: “Andrena salicifloris” is miner bee species in the family Andrenidae. The dossier treats that line as a proposition to test through Andrena, salicifloris and miner, not as a finished interpretation.
Why this record matters
The phrase “miner bee species in the family Andrenidae” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Mar 1, 2026. The linked authority identifier is Q2196836. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
