A drone fly [Eristalis tenax (Linnaeus, 1758] loaded with pollen grains is attempting to come out from a pumpkin (Cucurbita pepo L.) flower in an organic vegetable garden in southern Alberta, western Canada. It is important to inform that bees, butterflies and moth are not the only insect pollinators rendering cross-pollination services. Several species of beetles, wasps, ants and flies have also been reported to be effective pollinators. A vast number of our vegetables are dependent heavily upon insect pollinators for cross-pollination. Insect pollinators across different ecosystems are demonstrating an alarming decline with many species being threatened with extinction due to over-application of toxic pesticides in agriculture, pollution, climate change and global warming, parasitic diseases, colony collapse, lack of nectar foraging plants and suitable habitats. Conservation of insect pollinators is extremely important from the perspective of agriculture as they are responsible for pollinating several important food and industrial crops.
