Background

Xylocopa (Xylocopa) are medium sized bees, 16 – 25 mm in length, with black integumentintegument:
a tough, protective outer layer
covered by moderately thick brown to black pubescencepubescence:
short, fine hair
. Their wing are dark brown with vibrant green or blue iridescent reflections (Hurd and Moure 1963Hurd and Moure 1963:

Host associations

Xylocopa (Xylocopa) are generalist pollinators that have been observed visiting the flowers of many plant families including Actinidiaceae, Asteraceae, Brassicaceae, Convolvulaceae, Cucurbitaceae, Fabaceae, Geraniaceae, Grossulariaceae, Lamiaceae, Liliaceae, Lythraceae, Malvaceae, Nyctaginaceae, Oleaceae, Papaveraceae, Plantaginaceae, Rosaceae, Rutaceae, Solanaceae, Verbenaceae, and Violaceae (Vicidomini 1995Vicidomini 1995:

  • Malar area malar area:
    the shortest distance between the base of the mandible and the margin of the compound eye
    short.
  • Scutellum scutellum:
    shield shaped plate behind scutum
    gently convexconvex:
    curved outward
    in profile.
  • Hind tibiatibia:
    the segment of the leg, between the femur and the tarsus
    with two apicalapical:
    near or at the apex or end of any structure
    spines.
  • Male frontal carinacarina:
    a clearly defined ridge or keel, not necessarily high or acute; usually appears on bees as simply a raised line
    present and as a sharp ridge.
  • Male mandiblemandible:
    bee teeth, so to speak, usually crossed and folded in front of the mouth
    bidentatebidentate:
    having two teeth
    .
  • Male tegulategula:
    the usually oval, small shield-like structure carried at the extreme base of the wing where it attaches to the body
    with posterolateral third impunctateimpunctate:
    marked with punctures or pits
    and shining.
  • Male basitibial platebasitibial plate:
    a small plate at the base of the hind tibia, like a kneecap
    present and simple.
  • Female mandiblemandible:
    bee teeth, so to speak, usually crossed and folded in front of the mouth
    tridentate at apex
  • Female basitibial platebasitibial plate:
    a small plate at the base of the hind tibia, like a kneecap
    bifid at apexapex:
    end of any structure
    .
  • Female propodealpropodeal:
    the last segment of the thorax
    triangle present and distinctly differentiated.
  • Female pygidial platepygidial plate:
    unusually flat area (a plate) surrounded by a ridge or line and sometimes sticking well off of the end of the bee; if present, found on the sixth upper abdominal segment in females, seventh in males
    narrow, parallel-sided, and with subapicalsubapical:
    located just behind the apex of the segment or body part

    relating, pertaining, or attached to the side
    spines present.

May be confused with

Xylocopa (Xylocopa) are most similar to X. (Ctenoxylocopa) and X. (Biluna). Males can be distinguished by the combination of the tegulategula:
the usually oval, small shield-like structure carried at the extreme base of the wing where it attaches to the body
that is impunctateimpunctate:
marked with punctures or pits
in the posterolateral third, rounded scutellumscutellum:
shield shaped plate behind scutum
, and hind tibiatibia:
the segment of the leg, between the femur and the tarsus
with two apicalapical:
near or at the apex or end of any structure
spines. Females can be distinguished by the combination of their tridentatetridentate:
having three teeth
mandibles and hind tibiatibia:
the segment of the leg, between the femur and the tarsus
with two apicalapical:
near or at the apex or end of any structure
spines (Minckley 1998Minckley 1998:

Nesting behavior

Xylocopa (Xylocopa) has been recorded using a variety of materials for nesting, from dead trees to hollow stems and on rare occasions in the ground (Hurd and Moure 1963Hurd and Moure 1963:
