In Apis Mellifera or honeybees, the Proboscis Extension Reflex, PER, is part of the honeybee’s feeding behavior.   The PER is a natural behavioral reflex in which the honey bee extends its proboscis in response to antennal stimulation with a sugar solution, during normal foraging behavior, PER occurs when the honey bee finds nectar in a flower. For example, If a honeybee went out of the hive to find nectar in flowers, and then found nectar, it would stick its Proboscis out to sense and smell it. After the Proboscis senses it, the bee will collect the nectar and then bring it back to the hive. If this bee was impaired form the toxic Neonicotinoid, Imidacloprid, it wouldn’t be able to sense the nectar, collect it, nor bring it back to the hive. That is how Imidacloprid can affect a whole hive, just by infecting one honeybee and impairing its Proboscis Extension. The PER can be seen as one of the honeybees most vital tools. This is because, without it, the bee wouldn’t able to test if the substance it is retrieving is nectar, or another, poisonous, substance. Therefore the PER is vital to the honeybees survival and could mean life or death if it becomes impaired under the influence of the toxic neonicotinoid Imidacloprid. The PER happens as one swift motion in a honey bee, it is absolutely amazing to watch!

Honey Bee’s Proboscis by Christine R

bee photos, honey bees, proboscis

The bird’s water bowl and the top two tiers of my fibreglass pond dried up while we were away, even though the weather was predicted to be coolish.

Wandering around with the Nikon D3000 today, I spotted bees visiting the refilled ponds. I was surprised to see the unfurling of a red proboscis (tongue), not having photographed one before.
