Oatley Park Bee Walks
In July, Nikki Leung gave a very popular talk on Native Bees in Oatley Park, setting a new record for attendance numbers. This month, OFF took a different approach to its monthly field day, which was comprised of three small group tours of Oatley Park with Nikki. Although the limit of 5 per group meant we had to disappoint some people, those lucky enough to go experienced a close up and detailed introduction to the native bees of Oatley Park.
We learnt about the bees we saw busy at work on wattle, pea and hardenbergia. We inspected tiny bee nests in sandy embankments, old tree trunks and along some tracks. Our local native bees range in size from just 3 mm to 20mm, and are not impacted by varroa mite. They have benefited greatly from the drop in European honey bees, and this has helped to shore up our local biodiversity.
A tumulus is the loose dirt or soil pushed to the surface when ground-dwelling insects dig their underground tunnels. (eg ant nests). We learnt to identify bee tumuli, and watched fascinated as a female guarded each entrance, moving aside to let the busy workers come and go on their food forays.
Nikki has quickly developed an extraordinary level of expertise on our local bees - she has even found two as yet unpublished species! She has generously shared that knowledge with us, and her photography is outstanding. Huge thanks to Nikki.
