A little more than a week ago while I was admiring the showy pink blossoms blanketing the large George Tabor azalea bushes encircling a chestnut tree in my yard, I noticed scores of large carpenter bees visiting flower after flower. When I moved closer to floral show I realized that after the carpenter bees landed on the blooms, they immediately made the way down the outside of the blossoms to the junction of the petals and green sepals. As it turned out, the hefty bees were robbing nectar from the large trumpet-shaped flowers.
It seems carpenter bees are too large to fit through the throats of the bright pink blooms to reach the nectar located at the base of the blossoms. Faced with this problem, most other nectar feeders would abandon their quest for the nectar.
Such is not the case with these carpenter bees. These bees have the uncanny ability to obtain the nectar from the outside of a blossom. What I was observing was the bees chewing longitudinal holes at the base of each bloom and then dipping their tongues into the flowers’ sugary nectar.
Since I first noticed what was taking place I have closely examined a number of azalea blossoms and found any number of feeding portals created by the carpenter bees. In addition, my wife saw a wasp using a feeding hole after the carpenter bee that created it left.
Insects such as the carpenter bee are called nectar robbers simply because they feed on nectar without pollinating the flowers.
If you would like to witness this odd behavior, on a warm, sunny day, look for carpenter bees flying about your azaleas. When you spot them, watch where they go. After they leave, look for the feeding holes created by the bees.
I think you will agree you do not have to leave the confines of your yard to witness fascinating animal behavior.
