Yellow Trumpet Tree

This, I'd say was another of the triumvirate of Pantanal flowering trees in August, with the Pink Ipe and the Ant Tree.

  1. I wonder if the holes near the base of the flowers are from nectar robbers or just wear and tear. Posted 2 months ago
    1. Probably Christine, although parrots/parakeets are named as big consumers, but that damage doesn't look like parrot damage. See https://www.researchgate.net/publication/7662262_Extensive_consumption_of_Tabebuia_aurea_Manso_Benth_Hook_Bignoniaceae_nectar_by_parrots_in_a_Tecoma_savanna_in_the_southern_Pantanal_Brazil

      Not aware of flower-piercers there, though! Happy New Year!

      1. Interesting! Around here, we have some species of bees that cut small holes in the base of flowers to steal the nectar. I frequently see it with species such as this one:
        Dutchman’s Breeches - Dicentra cucullaria Clusters of white, pantaloon-shaped flowers on a leafless stalk that rises above feathery, basal leaves.<br />
<br />
These flowers are pollinated by early spring bumblebees, whose proboscises are long enough to tap the nectar. However, other bees with proboscises that are too short to reach the nectar usually just snip a hole through the outside of the flower at the site of nectar accumulation - this allows the bee to steal the nectar. Such nectar-robbing, however, doesn't bring about pollination.<br />
<br />
**Note the small hole on the right side of the bottom flower - this is a hole made by a nectar thief!<br />

        1. Thanks for the good wishes. Your photo certainly seems to show similar damage. The yellow trumpet looks to have a relationship with ants.


          However, this about T. aurea " nectar robbery (hummingbirds, Xylocopa and Oxaea bees). Similar to pollinators, nectar robbers visit larger inflorescences with a higher frequency" Larger bumble-bees appear to be the best pollinators.


          There's a lot here. https://academic.oup.com/botlinnean/article/181/4/667/2707845

          Thanks again

"Tabebuia aurea" is a species of "Tabebuia" native to South America in Suriname, Brazil, eastern Bolivia, Peru, Paraguay, and northern Argentina. The common English name Caribbean trumpet tree is misleading, as it is not native to the Caribbean. It is also known as the silver trumpet tree, and tree of gold.
