Transcript Pollinators PowerPoint

Flower Fly
Looks like a social bee or wasp
Antennae are short with a bristle on end
Has only one pair of wings
Cannot sting or bite
Considered a significant pollinator
Honey Bee
Social, lives in colonies in trees or hives
Used for honey production and ag pollination
Hairy, color is tan with varying degrees of orange
Carry pollen in pollen baskets on their hind legs
and it sticks to their hairy bodies
• Stings only once
• Drinks nectar honey and water through a long
Bumble Bee
Only social bee native to North america
Make nests close to or in the ground.
Large and very hairy
Yellow and black
Wings are clear with black veins
Can collect pollen and nectar from plants difficult
to get into (snapdragons)
• Can sting more than once
• Only the queen survives through winter
• Every part of their thin body is covered in
• Fly during the day when its warm
• Rest by folding their wings up over their body
• Drink nectar through a long tube called a
• Fly at dusk and night only
• Like butterflies, every part of their body is
covered in scales
• Have a plump body
• Spread wings flat when resting
• Attracted to light or white flowers that are
open at night
Leafcutter Bee
• A solitary bee
• Cuts neat circles in leaves and uses the pieces
to line their nests
• Builds nests in hollow twigs or other openings
about the diameter of a pencil
• Usually will not sting unless trapped
• Help pollinate alfalfa
Carpenter Bee
Females are bluish-black and can sting
Males are blond or tan and cannot sting
Over 1 inch long and as wide as your thumb
Nest in wood like dead tree trunks, firewood
or exposed wood on structures
Alkali Bee
• Solitary
• Pollinate alfalfa better than honey bees
• Important for pollinating flowers and eating
• Bright red, orange and pink flowers are more
visible to them than other colors
• Red, tubular shaped flowers are ideal
• Have the largest brain, heart, energy output and
breast mucsles in proportion to body size of any
• Nests are usually 1.5 inches in outer diameter
and they use them year after year
• Eggs are ½ size of a jelly bean
• Do their foraging at night and are attracted to
white or light colored flowers
• Pollen clings to their forhead as they readh
into flowers with their long snout and bristly
tongue to reach the nectar
• Responsible for pollinating cactus, bananas,
cashews, peaches, avocados, mangos and
other tropical fruits
• Nearly 1000 different species
• Clumsy when they fly and don’t see very well
• Attracted to flowers that are white or green and
either have a very strong scent or none at all
• The flowers they visit must produce a lot of pollen
so there is enough food as well as pollination
• Usually pollinate flowers with a large opening
where there is plenty of room for them to land.
