Brachythemis contaminata, also known as the Ditch Jewel, is a dragonfly species in the Libellulidae family found in many Asian countries. It is also known by the common names Asian Groundling, Asian Amberwing, Orange Skimmer, and Common Amberwing. This small dragonfly features brown-capped, yellowish-green eyes. Its thorax is olivaceous-brown, marked with a reddish-brown humeral stripe and two brownish stripes on each side. The wings are transparent but have a broad, bright orange fascia extending from the base to within 2 to 3 cells of the reddish pterostigma. The abdomen is ochreous-red, marked with dorsal and sub-dorsal brown stripes, and the anal appendages are reddish-brown. The female is similar to the male but in a pale yellowish-green color. The wings are transparent, tinted with yellow at the extreme base, but lack the bright orange fascia seen in the male. A female Ditch Jewel dragonfly was observed sitting on the leaf of a chili plant in Tehatta, West Bengal, India, on 31 March 2024.

The wasp-mimicking hoverfly (Mesembrius sp.) is bright yellow in color with black stripes and can be found in Australia, India, England, and the UK. There are three conspicuous black markings on the thorax, and the abdomen is banded with black and yellow. In the 2nd segment, the black bands are connected by a median band. The wings are tinted with a pale brown. This fly is commonly found either resting on leaves or feeding on flowers. Its warning colors are effective at mimicking a wasp. It has short antennae and a single pair of wings, indicating it is a fly. Hoverflies have smaller antennae and larger eyes than wasps and bees, with their eyes appearing to wrap around their head. The wing-vein pattern helps to identify it as a hoverfly. This photo was taken in a forest at Tehatta, West Bengal, India, on 07/03/2024.
