“Do you have a registered Pollinator Link® garden?”

As a registered Pollinator Link® garden you can become a Bee Guardian and citizen scientist researching ways to repopulate our city gardens with native solitary bees and answer the question: “How do I to get native bees to move into my Bee Home?”

Leafcutter Bee cocoon

Brisbane City Council sponsored the initial solitary bee home trial in three northside parks That trial proved the design works, with local Leafcutter bees using Native sarsaparilla Hardenbergia violacea for nesting materials. The design also survived Queensland’s storm season with no damage to the nesting tubes.

We are now recruiting gardens for larger city-wide trial will confirm those results and provide a core resource of Leafcutter bee cocoons to start repopulating urban habitats. Nesting tubes will allow cocoons to be collected and shared with new recruits.

The trial will again use a mix of different nesting tubes from Mason Bees UK and Crown Bees USA. Three different coloured Bee Homes will be used to test variations in nesting success.

Your Bee Guardian pack will include guides on where to place your Bee Home, suggestions on local bee attracting plants and guides to survey your garden and using iNaturalist to collect your findings.

Pollinator Link® fence sign

After the trial Bee Guardian packs are expected to sell for $88. So take advantage of the trial and order your Bee Guardian pack for $33: available to registered Pollinator Link® gardeners.

Want to participate in trial but not a registered Pollinator Link® garden? Register your garden today to take advantage of the trial price for you Bee Guardian home.

Butterflies in your garden

Jezebel Nymph Mynes geoffroyi

By: Michael Fox

Miranda a Fox Gully Bushcare neighbour sent me an exciting photo: a female Jezebel Nymph Mynes geoffroyi laying her eggs on a Native Mulberry Pipturus argenteus.

A close up look at her eggs shows an interesting and distinctive shape.

Native Mulberry fruit is edible and this tree was planted as part of our 2013 Community Gully Day with property owners and other community members coming together to restore the Fox Gully Wildlife corridor. Koalas Phascolarctos cinereus and Squirrel Gliders Petaurus norfolcensis are now breeding in the gully between the houses.

Cr Steve Huang is aiming to build on our community effort a wildlife bridge across Klumpp Road to Roly Chapman Reserve. Steve advised just last week that Federal Government funding has been sourced for a feasibly study.

Dainty Swallowtail
Dainty Swallowtail caterpillar

Look out for Dainty Swallowtail Papilio anactus checking out your backyard citrus as a place to lay eggs.

Like Orchard Swallowtail butterflies Dainty Swallowtail caterpillars are often found on cultivated citrus as well as Australian natives like south-east Queensland local Finger Lime Microcitrus australasica.

The caterpillars will not eat a lot of your fruit tree while they reward you with extra colour as these beautiful butterflies flit around your garden. The caterpillars have a curious defence mechanism extending orange osmeterium that produce a decaying citrus smell to discourage predators.

Mossies in your birdbath?

Mount Gravatt Environment Group

Toxorhynchites speciosus
and Culex sp. larvae

By: Michael Fox

Our Koala Drinker research has identified more than birds and Lace Monitors.

It is mosquito season so we regularly check the drinkers for mossie larva. Something we were not expecting was finding mossie larvae that feed on other mossies and not people. Adult Toxorhynchites speciosus feed on plant juices not blood.

Toxorhynchites speciosus larvae are huge, approx 25mm, by comparison with common mossie larvae like Brown House Mosquito Culex quinquefasciatus approx 8mm.

Check before you flush the mossie larvae in your birdbath. If you have some Toxorhynchites speciosus larvae perhaps scoop them out ready to return once your birdbath is refilled. Remember to also catch some of the small larvae to feed the mossie eating Toxorhynchites speciosus.

Bee Guardian Project – Stage 2 Trial

By: Michael Fox

Stingless Bee hive at B4C

I am often asked: “How do I to get native bees to move into my Bee Home?”

People are often thinking of the Native Stingless Bees Tetragonula sp. which, unlike solitary native bees, form colonies and make honey. The colonies can be housed in hives allowing people to purchase a hive to install in their garden.

Solitary native bees make individual nests which are filled with pollen and nectar: not honey, for the bee larvae to feed on when hatched.

Leafcutter and Resin Bee reports on iNaturalist

Bee Guardian Homes

.

We know from iNaturalist there are Leafcutter and Resin Bees in the Brisbane area. However, getting them to move into your Bee Guardian Home may take time. Therefore, we are researching ways to encourage Borders to move into your bee home.

.

Based on advice from Bee Scientist: Kit Prendergast the Stage 2 Trial will use a mix of yellow, blue and white bee homes to test any difference in take-up.

A mix of nesting tubes from Mason Bees UK and Crown Bees USA with removal inners will be tested again: 15 to 16 cm long 7mm diameter.

Removable inners create an opportunity to proactively bring solitary native bees to our urban backyards.

Similar to the Mason Bees UK and Crown Bees USA programs, filled tubes can be collected at a central location and replacement inners returned to prepare for the next season.

Filled tubes will be inspected then some returned and some used to send out to new Bee Guardians to hatch. Working this way we can maintain and build exiting populations while re-establishing solitary native bees in other urban spaces.

Initially Pollinator Link® gardeners will be invited to join Guardian Bee Home trial.

Native Solitary Bee Home Trial

By: Michael Fox

Australia has over 2,000 species of solitary native bees of which twelve have been identified within Mt Gravatt Conservation Reserve. My first introduction to these special locals was wondering about the green insect flying past while we were having coffee outside. A video captured this female Leafcutter Bee flying into the back of the cat’s scratching post with pieces of leaf rolled between her legs to make a nest for her eggs. Solitary native bees do not form colonies and make honey.

Guardian Bee Home with Bunnings Bee Home

The initial aim of the Pollinator Link® project was to create wildlife links between urban bushland with Water, Food and Shelter in backyards, balcony gardens, schoolyards, etc. Pollinator Link® team is proactively increasing invertebrate diversity with the Guardian Bee Home project and promoting the importance of Plant Local to Feed Local.

The support of Cr Fiona Hammond – Marchant Ward, allowed a trial of solitary Bee Homes based on the UK Mason Bee Guardian Scheme. Eighteen Guardian Bee Homes were installed in

and Terry Hanson Reserve at Chermside, and Crosby Road Bushcare at Albion.

Part of the trial was to test the effectiveness of the Mr Fothergill’s Small Bee And Insect House from Bunnings, which we believed were poorly designed: tubes too short and diameters too large, and likely to damage to our native bee population rather than help. Bunnings “Bee Houses” were co-located with with the Guardian Bee Homes for comparison.

(l-r) UK Mason Bee, Crown Bee tubes, paper straws
Leaf-cutter Bee cocoon

The target species for the Bee Homes are “Borders” like Leaf-cutter and Resin Bees which find a suitable hollow to make a nest. For the trial we used a mix of tubes from UK Mason Bees (7mm), Crown Bees USA (7mm) and simple paper straws (6mm) from BigW.

The tubes 15 to 16 cm long allowing for a healthy mix of female (laid first) and male eggs. Males bees hatch first then wait for the females to hatch. The females are also the most important: they do all the work, so having male eggs at the front of the tubes adds a layer of protection from attack by predators.

.

The UK and USA tube have removable inners that allow for filled tube to sent to a central location for processing and distribution to other locations. Replacing the inners each season reduces the risk of parasite build-up keeping keep the solitary bee population healthy.

Native sarsaparilla Hardenbergia violacea

.

.

.

Leaf-cutter Bees at Crosby Road Bushcare used leaves of Native sarsaparilla Hardenbergia violacea. The female cuts circular sections out of the leaves before rolling up to carry off to their nest site.

The most successful Bee Homes were installed between 1 and 1.5m above ground, received morning sun with shade during the middle of the day and afternoon.

.

.

.

Thanks for the nice home out of the rain.

The design successfully handled multiple storms without damage to the bee tubes. However, they did not survive the attention of an enterprising Ringtail Possum Pseudocheirus peregrinus who threw out the bee nesting tubes and moved in.

.

.

.

Ant invasion

As we expected the Mr Fothergill’s Small Bee And Insect House from Bunnings were not effective with some actually falling on the ground. The only insects that used these houses were Grass-carrying Wasps and ants.

Read the final report: Native Solitary Bee Home Trial

The next step is a larger scale Guardian Bee Home trial with Pollinator Link® gardeners.

Understanding community participation in urban conservation

By: Michael Fox

Understanding the motivations and challenges of community members already engaged in creating urban wildlife habitat, is a valuable step in building communications strategies to drive behaviour change across the broader community. Therefore, Jake Slinger’s university research thesis Understanding community participation in urban conservation is a valuable resource for our aim of registering 30,000 Brisbane Pollinator Link® to create over 800 hectares of city wide wildlife habitat.

The research was conducted by questionnaire sent to 276 community members who currently received the Pollinator Link® newsletter with participants limited to the Greater Brisbane region.

What lives in your backyard?

The top three motivations identified for creating habitat gardens are:

• General environmental interest: a general interest or concern for nature.
• Interest in flora/fauna: motivated by learning about flora and fauna.
• Inspired by others: motivated by friends and family and/or events.

.

.

Challenges of providing resources for pollinators include some hard to fix factors like Council regulation. However, participants suggestions point to a range of action we can take to engage and empower community members to create wildlife habitat in their backyard or on their balcony garden.

Engaging kids by helping them learn to see interesting butterflies, beetles and bugs then be citizen scientists recording their finds in iNaturalist.

Help SEQ gardeners learn to Plant Local to Feed Locals with free GroNative app for smartphones. GroNative allows uses to input postcode and suburb to identify plants that originally grew in that area.

We have a list of community nurseries that typically stock local natives however the research suggests we need to promote this more aggressively.

Helping people think differently about their gardens will help address “societal dilemmas” like balancing what looks good to neighbours versus what is good for pollinators: rather than have a scrubby untidy backyard build a unique garden feature that provides safe shelter and food for small birds.

Hovering Hawk Moths in your garden

By: Michael Fox

In 1862 Charles Darwin wrote to a friend at Kew [Gardens] “I have just received such a Box full from Mr Bateman with the astounding Angraecum sesquipedalia [sic] with a nectary a foot long. Good Heavens what insect can suck it”, and in a second letter just a few days later suggested “in Madagascar there must be moths with probosces capable of extension to a length of between ten and eleven inches [25.4–27.9cm]”. The Guardian

It was 130 years later that Darwin’s prediction was confirmed with the observation, in Madagascar, of Hawk Moth Xanthopan morganii praedicta using its 20cm tongue  or proboscis [prəˈbɒsɪs] to feed on orchid Angraecum sesquipedalia.

Video: Georgia Nierfeld

We have 65 species of hawk moths in Australia: like Georgia’s amazing Bee Hawk Moth Cephonodes kingii. While our hawk moths do not have huge 20cm tougues most are in the sub-family Macroglossinae: makros, large + glossa, tongue.  Their very long tongues (proboscis) allow them to hover in front of flowers while they access the plant nectar.

Hawk moths hovering in front of flowers are often mistaken for Hummingbirds which are only found in the Americas. The Bee Hummingbird is the smallest bird in the world and at 6cm it is similar in size to our Australian hawk moths.

Cute Domino Coukoo Bee found

Domino Coukoo Bee - Thyreus lugubris 2 - 1 April 2020

Domino Coukoo Bee Thyreus lugubris

By: Michael Fox

Bored being stuck at home?

Explore your backyard looking for  some of the 2,000 plus species of solitary native bees, or just admire the many butterflies that have appeared since the rain.

Domino Coukoo Bee - Thyreus lugubris - 1 April 2020

 

 

I found this cute and well named Domino Coukoo Bee Thyreus lugubris at my home. This find brings the count of solitary native bees found in Mt Gravatt Conservation Reserve.

 

Solitary Bee Homes - ver 5.0

Solitary native bees do not form colonies or produce honey. The females create a nest in hollows (Borders), make a nest in the ground (Burrowers) or chew a hollow in soft wood like Lantana stems (Borers).

The female bee then pack the nest with a pollen/nectar food mix then lay their eggs. In spring the next generation of bees emerge to pollinate our gardens.

Take a break to explore your garden and report your findings with the iNaturalist App on your smart phone.

Women dig in for the environment

20200308_160350By: Laurie Deacon

Sunday was International Women’s Day 8th March and I ran the usual Pollinator Link® bush corridor regeneration at Mount Gravatt State High School with the neighbours.

We had three wonderful young local women attend the weeding and planting. Two are mums, each with a toddler and a baby in tow.
