Butterflies are commonly said to have a symbiotic relationship with flowers. Mutualism is just one of three types of symbiosis and is characterized by each.

Plants have coevolved with many different animals to create symbiotic relationships. Pollinating animals include bees, butterflies, beetles, moths, hummingbirds, and bats. Bees and butterflies are important pollinating insects. Honey bees are the best known pollinators due to the important role they play in pollinating numerous food crops. Many of the farming practices we have developed are dependent on managed honey bee hives.

Perhaps less known is that lots of plants, not just food crops, need pollinators and that other species of bees and butterflies play a crucial role in their pollination. Bees and flowers Bees are the most prolific pollinators in nature. They spend the majority of their time searching for pollen and nectar as they are the main sources of food for themselves and their young. There are over 4, different species of native bees in the United States alone. Surprising to most, the honey bee is not one of them.

Honey bees were imported to North America by English settlers. Flowers that have evolved to attract bees as their main pollinators often are full of nectar and colored bright white, yellow, or blue. Bees cannot see the color red, which may be why flowers with red colors do not tend to attract bees.

Bees have branched hairs that pick up pollen while they are feeding. Some bees have even developed basketlike structures on their hind legs that allow them to carry pollen. A number of plants have evolved mechanisms that only allow certain bees to receive their nectar and pollinate them. For example, different species of bees have many different lengths of tongues. Some flowers store their nectar in areas inaccessible to bees with short tongues.

Other plants have evolved even more complex structures to keep certain pollinators from getting to their nectar. Snapdragons produce irregularly shaped flowers that keep nectar and pollen closed away. Only bees of the correct weight are able to open the flower to expose the nectar and pollen when they land on its landing pad.

Butterflies and flowers Unlike bees, butterflies can see the color red, so many of the flowers they are attracted to are colored bright red, pink, or purple.

Similar to bees, butterflies can see light in the UV spectrum and lots of the flowers that attract butterflies have areas that reflect UV light to guide the butterfly to the nectar. Butterflies are also lured to a flower by its fragrance. They use their feet to taste and need to land to feed.

The flowers that often attract butterflies have larger landing pads near the source of nectar. A butterfly drinks nectar through its proboscis, a long strawlike tube that is part of its mouth. The nectar of flowers visited by butterflies is often deeply hidden where only butterfly proboscises can reach.

As butterflies feed, they may also pick up pollen on their legs, mouth, and wings. When they travel to another flower, there is a chance the pollen will be transferred and reproduction will take place. Decline of pollinators Plants have evolved to depend on pollinators to reproduce. Without the animals that carry pollen from plant to plant, genetic variation would be greatly decreased and the survival of many species would be in question.

5 of the most famous symbiotic relationships between flora and fauna in the garden

Over the past few decades we have seen a measurable loss in the number of both managed and native bee populations, along with a decline in butterfly populations. We depend on pollination for many of our staple foods, as do many other organisms. Approximately one-third of the food produced globally is dependent on pollinating insects. The decline in pollinators can be attributed to many different factors. The butterfly lays it's eggs on elm twigs, and the caterpillars hatch a few days after the flowers appear on the tree in early spring.

When tiny they feed within the flowers, but when the flowers have withered and died they feed openly on the elm leaves. The adult butterflies emerge in mid-summer and spend most of their lives at the top of the trees, but occasionally descend to feed on the nectar of thistles and other flowers.

In a "normal" summer the females lay all of their eggs on the same individual tree upon which they fed as larvae. The same happens with most other butterfly species - in normal seasons they are surprisingly sedentary in behaviour, so much so that many species never fly more than a hundred metres or so away from their emergence site. In exceptionally warm summers, females still tend to lay most of their eggs on their home territory, but later disperse, migrating across the countryside in search of other suitable sites where they can lay their remaining eggs.

Sites for this species need to have an abundance of dog violets the caterpillar's foodplantand bugle the main nectar source used by the adults. The sites also need to meet fairly strict criteria regarding temperature and humidity. Furthermore, because the caterpillars hibernate during the winter, the areas where they feed must be exposed to sunlight at the critical stage when they reawaken in early spring.

The number of sites which fulfil all these criteria is very limited, so the butterfly is generally restricted to sunny clearings in woodland, where violets and bugle grow in profusion. Pearl-bordered Fritillaries Clossiana euphrosyne, depend on transitional woodland habitats Habitat management Woodland clearings are of course an unstable habitat - bare ground is quickly colonised by coarse grasses, then by bramble and bracken, or is replanted with new trees. Either way, the clearing quickly becomes overgrown, and the violets and bugle get shaded out.

When this happens, the clearing is no longer capable of supporting the butterflies. If they are unable to colonise another clearing in the immediate vicinity, the butterflies die out. When woodland management changes on a national scale, and becomes incompatible with the requirements of a particular species of butterfly, the result is that the species follows a trend of decline, and ultimately becomes extinct. The catastrophe threshold Each species has it's own "catastrophe threshold" - once the amount of suitable breeding habitat falls below a certain level local extinctions occur and the species contracts towards areas where more extensive areas of suitable habitat remain.

Even then the species often continues to decline because the gene pool is reduced.

Reduction, fragmentation and isolation of habitats means there is little or no opportunity for fresh genetic material to arrive, and ultimately the species is lost. If butterflies and other wildlife are to survive, it is vital that conservation and land management are coordinated at national level to ensure that sufficient areas of habitat are maintained in suitable condition throughout the country. It is also essential to ensure that existing areas of habitat are linked together by creating and maintaining a network of natural corridors woodlands e.

Symbiosis is defined as a mutually beneficial relationship between organisms. There are also many non-beneficial relationships, such as parasitism and predation, where one species benefits at the expense of another.

All stages of the lifecycle are threatened by parasitoids - creatures which feed on other organisms and eventually kill them. There are for example minute wasps which inject their eggs into the eggs of butterflies, feed on the developing larva within, and emerge as adult wasps from holes in the butterfly eggs.

Other wasps such as Apanteles and Ichneumon, and flies Tachina etc spend their larval stage feeding within the bodies of caterpillars, which die shortly after the parasitoids vacate them. Other tiny wasps, including the brilliant metallic green Pteromalus puparum, attack newly formed butterfly pupae.

Certain butterflies, particularly males of Meadow Brown Maniola jurtina, Marbled White Melanargia galathea and Common Blue Polyommatus icarus often have tiny red mites attached to them, usually on the thorax.

Studies have shown that the mites have no detectable effect on the flight performance, orientation ability or lifespan of infested Meadow Browns, so this could be regarded as a non-harmful form of parasitism. Orb spiders catch butterflies in their webs, and crab spiders lie in wait on flowers, ambushing them when they visit in search of nectar.

Vast numbers of caterpillars are eaten by birds, and lesser numbers by heteropteran bugs, solitary wasps, mantises, lizards, toads, mice and other predators.

For detailed information about predators and parasitoids see the Enemies of Butterflies pages. A butterfly may be capable of laying or so eggs, but in practice only about 50 are laid on average, as most females die before they are able to lay all their eggs. Probably 95 percent of those eggs will hatch, but at least 90 percent of the caterpillars will be eaten by birds, or killed by parasitoids, and fail to reach pupation.

At least half of all wild pupae will be consumed, be killed by parasitoids, or die from fungal attack. When the butterflies emerge from the surviving pupae, many more will be killed before they have time to mate and lay their eggs.

Butterfly populations are rarely stable though - poor weather during the flight season greatly reduces mate-locating and egg-laying opportunities, mild winters increase the likelihood of over-wintering larvae and pupae succumbing to fungal attack or viral diseases, and a succession of warm springs can have a very detrimental affect on species such as the Marsh Fritillary which over-winter as larvae: If the early spring is cold and sunny the caterpillars are able to warm themselves up by basking on dead leaves, which increases their metabolism, enabling them to develop quickly.
