Microcaddisfly
One of the smallest caddisflies, with adults only 3-4 mm long. Larvae build tiny purse-shaped cases from silk and algae on submerged rocks.
Did You Know?
Microcaddisfly larvae build a new case for each instar, and their final pupal case is so small it is barely visible to the naked eye.
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.
