DSC_0045  Flowerdale Landcare Beekeeping for Beginners Course

Yea Beekeepers

Yea Beekeepers is an informal group of some 20 or more bee enthusiasts that have been through a course run by Steve Joblin over the last 4 years. The beekeepers come together around four times a year to swap stories/experience and hold activities bee related.

The last meeting of the Flowerdale Landcare committee agreed to welcome Yea Beekeepers into the Landcare Group and to offer bee related activities as part of our Landcare calendar. The logic is that beekeeping is a livestock activity and one that requires learning about the natural environment in the task of honey production.

Our most recent activities were a Beekeeping for Beginners course and a Honey Harvest Day. The highlight of the Honey Harvest Day was not only extracting fresh honey, but also an interesting talk from our guest speaker Ric Stubbings on making Honey Mead. The tasting was also a highlight!

December/January is a great time for observing native bees and wasps. When everything else is looking for shade, these insects seem to be most active. The bee in this photo is actually one of a trio of native bee species that I noticed working a bank of  Black- anthered flax lilies (Dianella revoluta)273 on a hot December afternoon in Flowerdale.

This bee as far as I can identify, is commonly known as a Green and Gold Nomia (Lipotriches australica) and is a key pollinator associated with the Pale Flax lily (Dianella longifolia) and the Black- anthered flax lily. This bee, like most of the 1500 plus species of Australian native bees is a solitary bee, each female creating her own nest. By 277contrast  the European honeybee and the native stingless bees (Trigona carbonaria) are social bees that live as a hive with a queen bee. The Green and Gold Nomia constructs her nest by burrowing into the ground and creating cells. She places the pollen and nectar that she collects into the cell as provisions for the larva that will emerge from the egg she lays. Although solitary, she can share the entrance tunnel with other females of the same species.

The second of the trio that I noticed is probably one that is more familiar  in the Flowerdale are. This bee attracts attention with its short sharp runs and hovering in front of its flower target before darting in for a split second stay then darting off to the next flower. Commonly known as the Blue-banded bee (Amegilla cingulata), another solitary bee, it is highly attracted to blue flowers. It is another important pollinator of the  flax lillies. The Blue-banded bee has a peculiar method of collecting pollen through sonication also known as ‘buzz pollination’. Sonication is the rapid vibration of the muscles in the thorax between the wings that forces the release of pollen from the anther of the flower. The ‘buzz’ is quite audible. This bee is still around despite the Black-anthered flax lily having finished flowering. It can be seen visiting salvias, lobelia, lavender in the garden and tomatoes and strawberries in the hothouse. The Blue-banded bee is an effective pollinator of tomatoes and may be a back up if varroa mite enters Australia and decimates the European honeybee population.

The third of the trio caught my attention with its irridescent markings as it searched the clay bank looking like a predatory wasp. It was too elusive for me to photograph but can be found by going to www.aussiebee.com.au and looking for the Neon Cuckoo bee (Thyreus nitidulus).

As the name suggests, the Neon Cuckoo bee lays its egg in the nest cell of its host, in this case the Blue-banded bee, and then leaves. The unsuspecting Blue-banded bee does all the hard work of digging the nest burrow, storing provisions of nectar and pollen and sealing the cell only to have its own larvae starve as the Neon Cuckoo bee larvae make use of the food supply.

The moral of this story is that just by planting native lily species, you can create a small ecological community. The lilies need their native bees and the Neon Cuckoo bee needs the Blue-banded bee. More detail on this relationship can be found at www.aff.org.au/Duncan_Dianella_final.pdf.
