Did you know that certain native bees create bubbles. One such species are the Amegilla chlorocyanea in the act of “bubbling”. As Gary has said:
“Bubbling” is a process where the bee will regurgitate the watery nectar it has sucked up into a small ball, that it holds with it’s mouthparts, to evaporate the water out and condense it.

Check out our page on the Amegilla chlorocyanea Bubbling, wonderfully captured by Author Gary Taylor.
The act of when “a bee bubble” is a process by which the bee is thought to be concentrating the nectar that they have collected from flowers, making it more suitable for their needs. Whilst it is not certain that all bees do this, many native bee species are know to and have been seen blowing bubbles. As well as the species Amegilla chlorocyanea, the genus Lasioglossum, subgenus Homalictus and many of the bees from the family Colletidae are known to blow bubbles.
The expulsion of nectar to evaporate the moisture out to condense it can be seen with the following genus Exoneura on a Tamarisk. This bee is about 6 mm long and the one often referred to as a “Reed bee” as she likes to nest in hollow plant stems (such as reeds), although any hollow stem will do. Here we can see the clarity of the nectar bubble at the start (like any spherical lens it inverts the image behind).
In the following picture of the genus Homalictus, again on Tamarisk, this bee is smaller, at about 4 mm long, but just as gorgeous with her stunning metallic green (that changes to stunning gold or incredible copper red depending on the angle of the light on her). This picture shows how she uses her glossa (that’s just scientific for “bee tongue”) to hold and stretch the bubble for faster evaporation. In layman’s term, they blow and suck the nectar in and out, until it’s a bit like Nestlé’s sweetened condensed milk.
In this picture is the genus Lieoproctus, possibly plumosa. This one shows the colour change that comes with the condensing of the nectar, as evident in the bubble.
In the following image, we can see Hylaeus (Gnathoprosopis) euxanthus creating “yellow coloured bubbles”, the colour being derived from pollen in the mixture.
The following Wasp mimic bee (Hyleoides concinna) was seen bubbling at the Australian National Botanic Gardens n Canberra, ACT.
