A honey bee extracts nectar from a flower using its proboscis.
From the en.wikipedia.org
To feed, the hawk moth unrolls a long proboscis, sticks it in a flower like a straw, and slurps up nectar.
From the npr.org
The space leading to the nectar in each flower is just large enough for the proboscis of the bees that pollinate them.

These bees will then associate the smell of clover with nectar, and the scent of a clover flower will send them into a frenzy of proboscis-extension.

To the mirth of his colleagues, Darwin postulated that there must therefore exist a moth with a 25cm-long proboscis, specially evolved to sup the nectar and thus pollinate the flower.

Fortunately, the bug's proboscis cannot penetrate the skin of animal or human, and the adult depends for food only on flower nectar and plant detritus.
