Mealybug Destroyer
A dark-colored Australian ladybird with an orange head, widely used as a biocontrol agent. Its larvae are covered in white waxy filaments that mimic their mealybug prey.
Did You Know?
Larvae are often mistaken for the very mealybugs they are consuming due to their waxy white coating.
Water Measurer
A very slender, elongate semi-aquatic bug that walks slowly on water surfaces in the Americas. Its head is exceptionally long and narrow with a small rostrum at the tip. It moves with slow, deliberate steps along pond margins.
Did You Know?
It is so lightweight that it can walk on the water surface without breaking the surface tension, leaving no visible dimples where its feet contact the water.
