- The majority of flowering plants encourage insects to visit their flowers by secreting a sugar-rich liquid called nectar. This nectar collects in pools, below the sexual organs of the plant. As the insect enters the flower in search of nectar it brushes against the anthers (pollen bearing male parts of the flower).

- Bumblebees. Bumblebees can vibrate their bodies to dislodge pollen from a flower. The bee then combs the pollen off its hairy body into little baskets on its legs, called corbiculae.
- Hoverflies. Hoverflies are prolific pollinators. They are known to visit at least 72% of global food crops and over 70% of animal-pollinated wildflowers.
- Solitary bees. Solitary bees don't travel very far, although foraging distances vary among species. Most forage up to 500 metres from their nest and some as little as 100 metres.
- Wasps. Wasps are hungry minibeasts with high energy needs, so many of them search for flower nectar. Wasps are not as hairy as bees, so pollen does not stick to them as easily, but they are still important pollinators.
Bees and flowers. Lots of plants rely on insects like bees to reproduce. To make a seed, a flower needs to be pollinated. Pollen from one flower needs to travel to another. Bees are...
May 24, 2017 · Since plants can’t move, they have to employ other tactics to ensure pollen is carried from flower to flower. Some plants rely on wind and water, most flowering plants reproduce through animal pollination.
Aug 27, 2023 · Insect pollinated flowers play a vital role in enhancing genetic diversity within plant populations. When pollen is transferred between different flowers or even different plants, it introduces new genetic material, increasing the genetic variability of offspring.

When visiting flowers, pollen sticks on to the body and legs of the insect. The pollen is then transferred from the male parts of a flower to female parts, enabling pollination to take place. Read more about the process of pollination.
Depending on insect species (or indeed bird or animal pollinators - bats and hummingbirds, for example, are known to pollinate flowers), plants have various characteristics that will attract the target pollinator. They are known as pollination syndromes. These may include: 1. reward - such as nectar and pollen 2. scent 3. visual cues - colours and ...
It's clear that insect pollination is vital for landscape and habitat diversity. Many plants, flowers and trees depend on insects to create seeds and fruits (from applesto various wild hips, nuts and berries) upon which humans and wildlife depend. However, when considering the value of insect pollination, usually it is only the economic benefit to ...
Many insectsplay a role in pollinating crops, but also flowers, trees, shrubs and hedgerows. Bees are the mostly widely understood pollinators, and honey bees have long received recognition for the pollination service they provide. Honey bees are essential for pollinating crops like almonds. Read more about honey bee pollination. However, increasin...
In Europe: 1. It is estimated that 84% of EU crops (valued at £12.6 billion) and 80%of wildflowers rely on insect pollination. (source: Buglife) 2. Across Europe 38% of bee and hoverfly species are in decline, and only 12% are increasing. (source: Buglife) 3. 24% of Europe's bumble bees are believed to be facing extinction according to one report. ...

Beetles frequently visit magnolias and flowers close to the ground. Butterflies: Butterflies often visit round flowers with flared petals that lead to narrow throats that conceal nectar. Butterflies land on the wide petals, then delicately probe the flower’s nectary (the gland that produces nectar) with their long proboscis (tongue).
It is estimated that 65% of all flowering plants and some seed plants (e.g. cycads and pines) require insects for pollination. This percentage is even greater for economically important crops that provide fruits, vegetables, textile-related fibres and medicinal products.
