Background

Pseudoanthidium bytinskii are medium to small, 9 – 10 mm bees. They have black integumentintegument:
a tough, protective outer layer
with extensive yellow markings on their head, thorax, legs, and abdomen. They have thin white pubescencepubescence:
short, fine hair
that covers their body (Warncke 1980Warncke 1980:
Warncke, K. 1980. Die Bienengattung Anthidium Fabricius, 1804 in der Westpalaarktis und im turkestanischen Becken. Entomofauna 1: 119ndash;210.
).

Diagnostic characteristics

  • Axilla axilla:
    the triangular or rounded point on the thorax where thoracic muscles meet the forewing of an insect
    spined.
  • Female mandiblemandible:
    bee teeth, so to speak, usually crossed and folded in front of the mouth
    seven-toothed.
  • Male T7T7:
    the segments on the top side of the abdomen, often abbreviated when referring to a specific segment to T1, T2, T3, T4, T5, T6, or T7
    with broad emarginationemargination:
    a notched or cut out place in an edge or margin, can be dramatic or simply a subtle inward departure from the general curve or line of the margin or structure being described
    .

of Pseudoanthidium bytinskii make it easily distinguishable from other P. (Pseudoanthidium).

Nesting behavior

Little is known about the nesting biology of Pseudoanthidium bytinskii but most species of Pseudoanthidium nest in pre-existing cavities in wood, stems, galls or crevices (Litman et al. 2021Litman et al. 2021:
