Start bee and fly watching. Bees and Flies pictured in this guide. Bees Anthophila. Bee Flies Bombylidae. Hover Flies Syrphidae. Recommended Reading. Sphaerophoria philanthus , Iceberg Point, Lopez Island Bees as well as flies also have three tiny simple eyes on the tops of their heads ocelli that detect brightness and moving edges, rather than color, so they are useful for orientation during flight, and early detection of approaching predators, but not in choosing flowers.
Flower aroma is another signal. A gene which has profound effects on the production of seeds has been identified by researchers. As the weather cools in autumn, you may notice the process of condensation, with water droplets forming on windows. Researchers have found that a similar process — biophysical condensation - is happening inside plants and allows them to sense fluctuating temperatures.

Starting my own group is the culmination of a long journey. More News Stories. The wind may pick up pollen from a grass flower and scatter it all over the place. Only by chance will a little pollen land on another flower of the same species. To make up for this waste, wind-pollinated flowers produce a huge amount of pollen, as hay fever sufferers will know. Wind-pollinated flowers tend to have small dull-coloured petals or, in the case of grasses, no petals at all. The pollen grains are not sticky like those of animal-pollinated flowers, which reduces the chance of them sticking to leaves and other obstacles.
The stigmas of receiving flowers are sticky in order to hold on to pollen carried by passing breezes. Add to collection. Go to full glossary Add 0 items to collection.

These insects make good pollinators because they share two important features: They fly, and so are capable of visiting many plants in a relatively short amount of time They are motivated to interact with pollen, as they either eat it or food items located nearby e. How do insects pollinate plants?
Pollination by pollen-feeders Many insects eat pollen. Disadvantages of attracting a pollen feeder: They eat the very item the plant wants delivered - pollen. They tend to be generalist feeders and eat other parts of the plant, including the sexual organs. They could be considered to be 'unreliable pollinators' as the pollinator might not go anywhere near the female organs of the same species of plant. Pollination by nectar feeders The majority of flowering plants encourage insects to visit their flowers by secreting a sugar-rich liquid called nectar.
Advantages of attracting a nectar feeder: The locality of the nectar ensures the insect cannot avoid touching the organs associated with pollination. Pure nectar feeders such as butterflies and moths do not eat the pollen.
