This freshwater critter mix contains a wide range of food for your fish critters like Mayflies, Damselflies, Free-living caddis, Leptofleb mayflies, Stick Caddis, Stoneflies, Waterboatmen and more.
Damselfly larvae are similar to dragonfly larvae, to which they are related, but are more slender and have a long tail tipped with three fanlike gills.
Leptofleb nymphs are characterised by a flattened head, body and legs which decrease their fluid resistance and helps them to avoid getting washed away in the fast-flowing rivers and creeks where they live. They can also be found in slower-moving lowland rivers, lakes and dams.
Leptocerids are one of the most common families of caddisflies in Australia, and like most members of this family, the larvae make protective cases from debris found in their freshwater environments.
One of the most common groups of this family found in Melbourne are known as ‘stick caddis’, due to their habit of making a case by chewing out the inside of a stick or plant stem.
Stonefly larvae are characterised by long antennae, two sets of wing-pads and a two-pronged tail. The larvae of many stonefly species have a tuft of feathery gills at the end of the abdomen.
Hydrobiosids are free-living members of the caddisfly family – a group usually distinguished by its larvae, which use constructed cases for protection.
Waterboatmen are aquatic bugs who propel themselves through the water with their paddle-shaped hind limbs. These are small bugs (up to 12mm), usually coloured dark brown with rounded triangular heads and large compound eyes that wrap around the sides.
