GLOSSARY

AbdomenThird segment of an insect.

AntennaeSensory structures that receive and process volatile substances responsible for scent and taste. They also perceive vibrations, air movement, temperature, and humidity. Composed of three segments: scape (base), pedicel (stem), and flagellum.

AntherMale structure where pollen is located on a flower.

AroliaSoft pads between the tarsal claws.

Batesian mimicryResemblance of a harmless species to a poisonous species that shares a common predator, imitating the signals of the poisonous species.

CarnivorousMeat-eating.

CarpelOvule- and seed-producing organ in a flowering plant.

CorbiculaPollen basket on the third pair of legs.

CorollaPart containing all of the petals of a flower.

CoxaPart of the leg closest to the abdomen.

CropPrestomach organ that stores food in an insect.

ExoskeletonProtective covering over the body.

Facial foveaeSmall depressions or grooves in the face.

FemurMiddle part of the leg, past the trochanter and before the tibia.

FertilizationJoining of the sperm and egg.

FilamentStructure on which a flower’s anther is located.

FlagellomereSubunits of the flagellum.

FlagellumWhiplike end structure of antenna.

GameteSex cell.

GametophytePlant structure that produces egg and sperm cells.

GlabrousSparsely hairy.

HamuliSpecialized hooks that connect the two wings together.

MicrosporeIn a plant, the spores that develop into pollen.

Müllerian mimicryResemblance of two or more poisonous species that share common predators, imitating each other’s warning signals.

NectarSugar-rich liquid produced by plants.

Nectar guidePattern or coloration on a flower’s petals that directs a bee toward the nectar.

NectaryPlant structure that produces nectar.

OcelliSimple eyes that register intensity, wavelength, and duration of light.

OvaryPlant structure containing the ovules. It eventually becomes the fruit wall.

OvipositorOrgan used for laying eggs. It also functions as the stinger.

OvuleStructure that contains and produces female reproductive cells in a plant. After fertilization, the ovule becomes the seed.

PistilFlower organ made up of the stigma, style, and ovary.

PollenMale gametophytes in a plant.

PropodeumFirst abdominal segment. It is fused with the thorax.

Pygidial platePart of the last tergum of a bee. It is often flat and bounded by ridges. It is often triangular in shape.

ScopaPollen-carrying structure on a bee. The plural is scopae.

SpiraclesSmall holes in the exoskeleton.

SternumBottom plate on the abdomen of the bee. The plural is sterna.

StigmaReceptive tip of the carpel or of several carpels of a flower that receives the pollen grains.

StyleStalk that pollen tubes grow through to reach the ovary. The stigma is usually on the end of the style.

Subantennal suturesSutures below the antennae.

SutureSeam between plates in the exoskeleton of an insect, usually seen as a line.

TarsusEnd part of the leg, below the tibia.

TergumUpper plate on the abdomen of a bee. The plural is terga.

ThoraxSecond or middle segment of an insect. The thorax includes the legs and wings.

TibiaMiddle part of the leg, below the femur and above the tarsus.

Tibial spurSpiny projection from the tibia.

TrochanterMiddle part of the leg, between the coxa and femur.
