Pollinators

Beneficial Insects, Bees and Wasps

Among the many different beneficial insects you’ll see in your xeric garden, none are more crucial to the survival of the human race than pollinators.

The domestic honeybee and the many species of wild bumblebees are just some of the pollinators going about their business every day throughout the summer.

Not all of these insects collect nectar to make honey for a food source for the winter; some of them live solely on pollen; others simply provide their offspring with a survival mechanism while the adults die when cold weather arrives.

Many small bees provide a valuable service in our gardens and orchards. Notable among them are solitary bees, Mason bees and bluefaced bees.

Small and insignificant at first glance, the sheer numbers of plants that rely solely on these tiny pollinators to help them produce their fruit is astounding.

Wild bees can pollinate many times the number of blooming plants than honey bees, so enticing these skilled workers to your garden by providing for their needs can be a huge benefit.

How can we attract pollinators?

These tiny bees don’t live in a hive with a tight social structure like their larger cousins, the bumblebees and honeybees. They sometimes live communally, building their nests and occupying the same area in search of food, but they don’t have a hierarchy.

Each female bee provides for her offspring by laying a single egg in a chamber dug out of a clay bank or in the pith of a twig, then seals up the egg along with a ball of pollen and nectar to sustain the larvae until it undergoes metamorphosis and pupates, hatching out as an adult the following spring.

Pollinators require a nectar source, which luckily can be provided by many of the same plants for bees that we already like to grow in our gardens.
A clay soil which they can mix into the right consistency with their saliva for sealing up the egg chambers can be provided by keeping a small area of your garden bare of mulch.
Judicious neglect in the form of leaving twigs and small branches in an out of the way corner for them to use as a brooding area will help, and in some cases, a custom made brooding chamber made from a block of wood with small holes drilled to a depth of about 5cm. A critical factor is a roof or overhang to keep the clay plugs dry.

Mason Bee House to Attract Pollinators

**Wooden spools with Mason bee larvae**

Here's a craft that I made to help the Mason bees feel right at home in my garden.

**Mason bee brood house**

A friend gave me two boxes of turned wooden spindles to use in my salvaged garden art, and on closer inspection, I realized that they were plugged with a clay like substance.

It was exciting to realize that they were Mason bees.

After unplugging one of them to be sure, and not one to look a gift horse (er, bee) in the mouth I made several mason bee brooding houses.

Hanging these in areas around the garden where the newly hatched bees will find some nectar rich plants will ensure that they hang around and pollinate all my plants, and in turn use them to hatch out future generations of this precious resource.

Insects in the Xeric Garden...

...where would we be without them?

Insects like butterflies and bees are an obvious benefit to us - but what about all the other little flying and crawling insects and bugs that we don't pay much attention to?

They're useful too, and they deserve more of our respect - after all, they do a good job of pollinating, scavenging, cleaning up the dead, and preying on overpopulated pest insects.

See more about Insect Identification and the Insect Encyclopedia here.

Planting a nectar corridor or butterfly garden will attract many insects - butterflies, bees and other pollinators will flock to the colourful blooms for the nectar, and other plants will be used as butterfly food by many species.

Make sure when you plan your xeric garden, you leave some room for these incredibly helpful, and fascinating creatures, the insects, and the many spiders that use them as a food source.
