Macro and Micro Picture of the Day 2020-03-06

Here are catnip flower buds. They are about 2.3 mm wide. The most abundant phytochemical in essential oil of catnip, nepetalactone, attracts cats, but repels mosquitos and flies.

Equipment used: Canon EOS Rebel T5i with a standard zoom lens (EF-S 18-55 mm) on a 49 mm long extension tube.
