“Build it and they will come”

This morning as I sat on my back patio looking around at the back garden drinking a coffee, a butterfly almost landed on my head. How delightful that sensation was once I had got over the initial shock response! I watched it fly away and cross the path of two other butterflies in the process. As I reflected on the growing number of insects I have been seeing in my garden lately I was reminded of a conversation that I had with my sister yesterday. Somehow the conversation got around to the praying mantis egg case that I had discovered before and after hatching. She commented on how lucky I am to have that happen in my very own garden and told me that her husband’s brother had just bought a praying mantis egg case because he couldn’t seem to attract them to his garden. She asked me what I was doing that I thought might be helping them thrive in my garden. The truth is that I am not really sure. I think that a garden is such a complex system with such an abundance of variables that it’s hard to isolate one or two things that make a difference, but here are the things I think are making a difference.

  • I garden organically with no insect control whatsoever, not even white oil. The only way that insects die in my garden by human hands is by being accidentally squashed, squished, crushed or eaten (note: accidentally!). Otherwise I leave it to other predators in the food chain and I think the birds are quite happy about that! Not to mention the praying mantises and lacewings.
  • I try to put the beneficial insects and suffering plants in the same vicinity. For example, the Lacewings seem to like laying eggs on my clothesline pegs so I simply take them off the line and peg them to a plant with scale or aphids. Lacewing nymphs will eat each other in the absence of a ready food source so I figure that I am not only controlling aphids and scale I am also maximising the population of their main predator. I am not worried about being taken over by lacewings either, because the birds seem to appreciate them as a snack. Recently I “saved” two Tuckeroo saplings with this method. It was fascinating watching the transformation as the Lacewings took over the aphid and scale populations and the saplings grew new healthy growth. Both trees are thriving now!
  • I make an effort to maximise biodiversity in my garden. An obvious way to do this is to plant a variety of species and I do that with an effort to preference endemic and native species. I also remove or control invasive species to stop them smothering other plants, particularly the endemic plants in our natural bush gully.
  • I let some of my annual herbs and leafy vegetables flower. Basil and lettuce in particular seem to attract so many beneficial insect species!
  • I leave piles of “garden debris” for nesting purposes. My garden isn’t tidy, because gardening for me is more about the wild delights of nature. Apart from that I’m busy and I’d rather have a messy, wild garden full of biodiversity than a tidy collection of low maintenance species. I don’t have a problem with the latter… if it floats your boat go for it!

This issue of insects is an important one. A quick google search reveals an alarming number of studies showing a decline in insect populations around the world. Without insects, other species in both plant and animal kingdoms won’t last long. I would love to see a revolution in the way that we think about them so that we can celebrate their place in the system and all the benefits we reap due to their “little” lives.
Gardening, for me, is therapy and that therapy is far more effective when it’s full of a delightfully wild variety of things that grow, glow, climb, bloom, crawl, sing and fly, but more than that it’s about the surprises, the astonishment and all the amazing learning about this wonderful thing called life!

Sweat Bees – Nomia and Lipotriches

These buzz pollinators are in the Halictidae family. All of the Halictidae bees are said to be attracted to perspiration, explaining the common name of “Sweat Bee”.

Unlike other buzz pollinators discussed in this blog, bees in the Nomia genus have hard enamel-like bands rather than hairs. The hairier bees in the Lipotriches genus used to be classified as Nomia, but have since been split into their own subgenus.

A Nomia bee with “enamel” stripes – do you see it “bubbling”? This is a process that the bee uses to dehydrate the nectar being collected for her nest.

The males are commonly observed roosting together on twigs. According to AussieBee, there are often hundreds and sometimes thousands roosting together. I only wish that I could find where they roost in my garden!

Below is a video that features footage of a tiny Lipotriches bee foraging in my garden.

The Green and Golden Amegilla aeruginosa

At first sight in my new Far North Queensland garden I was shocked by this bee. It had all the hallmarks of Amegilla but no bands like Blue-banded Bees and it wasn’t a Teddy Bear Bee. Kit Prendergast, an Australian scientist who researches bees, came to the rescue with an identification.

Despite being first described in 1854, these bees have not attained a common name. Perhaps this is because they are not as obviously spectacular as some other Amegilla species. A close look, however, reveals the same amazing eyes and furry body with turquoise hairs on the thoraz and a lusciously golden abdomen.

The species is only found in the North of Australia and is slightly smaller than other Amegilla species. I have seen it referred to as the “Green and Golden Bee” on a rare occasion, but this fails to grasp the splendour of this little character.

These bees appear to love Basil and I often see them foraging around the long flowering stalks. I even saw one being devoured by the Praying Mantis that uses the Perennial Basil patch as a hunting ground. (If you’re interested, you can see that video here.) It was easily recognisable from the showy golden abdomen grasped by the Mantid.

Leafcutters and Resin Bees

Leafcutters and Resin Bees are both in the Megachile genus.

I’ll never forget the first time I saw precisely cut leaves poking out of a hole in my bee hotel. This was my first encounter with a Leafcutter Bee and I’ve not had many encounters since.

They are elusive and fast, both while cutting the soft leaves that they use to line their cigar shaped nests and flying back to a nest with them. I managed to capture it on video one day. You can watch it here. Note how even the slow motion looks fast!

Leafcutters favour soft thin leaves and have a preference for rose leaves. It’s easy to recognise the regular half moon shapes around the edge of the leaves – far too regular for a grasshopper, caterpillar or leaf beetle!

Here’s a link to a video on YouTube showing a Leafcutter cutting a Rose leaf.

Some companies even sell them for release! Check out this video showing a release.

Resin Bees use resin to seal their nests which are usually made in abandoned borer holes in wood or in bee hotels. The resin comes in many different colours. I’ve seen white cellophane like seals and bright green ones as well as the amber that we usually associate with tree resin.

All Megachile bees show a preference for pea flowers, perfectly shaped for them to harvest pollen and nectar, but they also like flowers with purple pollen and I often see them on my Perennial Basil.

Tiny Buzz – Homalictus Bees

Most of the bees in this subgenus (of genus Lassioglossum) are less than 8mm long. The one in the feature photo (Homalictus urbanus) is between 4 and 5mm long! She is foraging from a tiny Commelina flower.

They have relatively short tongues so prefer open “flat” flowers where it’s easy to reach pollen and nectar.

Homalictus have been known to share their burrows, though each individual contributes eggs rather than having a queen like European Honey Bees and Stingless Bees. Scientists have even discovered a Homalictus urbanus burrow being shared by 160 bees!

Australia’s Cuckoo Bees

These criminals of the bee world are deceptively beautiful. They buzz through the garden, bright colours or patterns grabbing the attention of the attentive gardener, but they work against other bee beauties.

They are also known as “Cloak and Dagger Bees”.

Coelioxys species use the newly built nests of Megachile species to lay their own eggs. The young hatchlings consume the nutrients left for the Megachile babies much like the cuckoos of the bee world.

Spectacular Thyreus species follow the Amegilla species and take over their burrows for their own young.

The Neon Cuckoo Bee (Thyreus nitidilus) is a delight of bright blue that tempts any nature photographer to stall and click away until the bee leaves. Click here for a slow motion video as one forages on Perennial Basil.

The paler blue of the Chequered Cuckoo Bee (Thyreus caeruleopunctatus) and the spots that give it its common name are likewise intriguing.

The Domino Cuckoo Bee (Thyreus lugubris) is similar to its chequered cousin but her patterns are black and white.

Regardless of their ominous intent, they are lovely to observe and any contribution to biodiversity is hopefully positive for all organisms.

Australian Mellitidia

Who will solve the Mystery of the Australian Mellitidia?

Just look at that gorgeous bee! She’s small, gold and awfully busy. She doesn’t care that “busy” is a bee stereotype. She has more important things to worry about.

She’s probably nesting in ground burrows.

From my observations, she appears to be a buzz pollinator.

She is thought to be a solitary rather than social species.

She’s the only Mellitidia found in Australia, and even then, she’s only found in the Far North.

iNaturalist just says, “Mellitidia tomentifera is a species of insects with 67 observations”.

There are a few photos here and there on the internet. There are little snippets of observation and some complicated scientific papers, but little else.

Perhaps I can watch and photograph and record my observations and be the first to record some of her special features to share with the world!

Australia’s Largest Bee – The Great Carpenter

Scientific Name: Xylocopa (genus)

She sounds like a jet engine in comparison to other buzz pollinators. He probably does too, but I’m yet to find a male! At around one inch or two and a half centimetres long, the Great Carpenter Bee is Australia’s largest bee and yes, they are capable of stinging. They don’t usually sting though. Like most Australian native bees that have stings they are not aggressive and will only sting in defense.

The male is a glorious gold similar to a giant Teddy Bear Bee but he has green eyes rather than the amber typical of a Teddy Bear.

There is now evidence to suggest that Great Carpenter Bee daughters stay in nesting burrows and help their mother to provision and guard their siblings as they develop.

Masked Bees – Hylaeus Bees

Hylaeine Bees are found on EVERY continent except Antarctica.

They have facial markings that resemble the emarginate eyes of wasps. More than 200 species are distributed throughout Australia.

The facial markers that earn them the “masked” label are usually more elaborate in males.

They usually nest in holes in wood, made and abandoned by borers. Some nest in crevices in rocks. They line the nest with cellophane-like fibres.

Teddy Bear Bees

This shy species is very difficult to find in the garden. Like most Amegilla species, Teddy Bear Bees are quick and fly in erratic patterns, probably to elude predators. With their audible buzz and golden colouring they are sometimes mistaken for Bumblebees.

While each bee provisions a nest by herself, Teddy Bear Bees have been known to nest closely to other females. They are also known as Golden-haired Mortar Bees, giving a clue about their nesting behaviour. They tend to nest in hard soil, favouring locations like creek banks. They have also been known to nest in between bricks with soft mortar on occasion. Each nest contains small chambers which are carefully provisioned with food before an egg is laid.

Males roost on reeds or branches at night, sometimes with other males.

Also known as:

  • Amegilla bombiformis
  • Golden-haired Mortar Bee

They are very similar to Banded Bees but have strikingly different colouring. Like the Blue-banded Bees, their nests are sometimes invaded and taken over by Cuckoo Bees.

Blue-banded Bees

Despite being called “Blue-banded Bees”, many banded Amegilla species are not blue at all but range from blue to white and possibly green!

I have heard it said that they are Australia’s most photographed bee and it’s no surprise! With their amazing eyes, iridescent bands and alluring buzz they make great subjects. The iridescent bands are actually tiny diagonal stripes on the hairs of the abdomen that make them shine and sparkle as the light reflects.

They nest in burrows in hard soil walls or soft mortar on their own but often amongst other nests. Sometimes these nests are taken over by Cuckoo Bees.

Research studies suggest that their ability to buzz pollinate (also known as sonification) increases yields on many plants including tomatoes and blueberries.
