Not only Hummingbirds. Dragonflies and Hoverflies can also fly backwards.
Pollinators include many types of insects such as bees, butterflies, hoverflies and others, but also bats, birds and lemurs.
Yes, hoverflies nest in compost. The insects in question (Syrphidae family) may be attracted to compost heaps, piles, and piles and to uncovered compost bins and containers. They particularly will be attracted to carbon- and nitrogen-rich materials -- especially kitchen scraps and plant parts -- which are in the process of breaking down into dark-colored, fresh-smelling, nutrient rich humus.
Many insects have hair on their eyes- the best example is a honey bee but many butterflies, flies and hoverflies also have hairy eyes. LordV
The larvae eat Aphids The adult Hoverflies eat pollen and nectar from various plants
Andrew John Hart has written: 'Overwintering and developmental biology of the hoverflies Episyrphus balteatus- DeGeer -and Syrphus ribesii- L. - - Diptera, Syrphidae -'
Yellow and syrphids (hoverflies) are of a similar size and color, though a yellow jacket is more yellow than a hoverfly. Their wings are also simiilar, looking tranluscent with veins running through them.
Quite a few. The main classes are Hymenoptera (bees, colonial and solitary), Lepidoptera (butterflies, moths), and Diptera (flies, mainly hoverflies which disguise as (bumble)bees). Feeding on pollen isn't as common as feeding on plant sap or leaves though.
Some harmless organisms have become adapted to look like dangerous species. This is called mimicry. For example, stingless hoverflies have black and yellow bands on their bodies that resemble those on wasps or bees. This warns predators to stay away, even though the hoverfly is incapable of stinging.
aphids provide a base to the food chain, attract ants that aerate and carry nutrients through the soil. hoverflies lay their eggs amongst aphid colonies the larvae consume aphids then go on to become important pollinators as adults.
Cows, horses, sheep, ducks, llamas, alpacas, buffalo, birds, moles, rabbits, most bugs, voles, worms, and if there is a stream in the meadow, you also have to consider fish and other types of smaller aquatic animals. Birds which live in or near meadows include sparrows, finches, hawks and other birds of prey.
Hover flies can be killed in various ways. For example, most kinds of insect sprays should be able to kill them.
