The insect could be a Mortar Bee. It looks more like a wasp with Bee colouration. They tend to be solitary females that bore into soft rock, earth or weak mortar. They don't swarm and the female lays eggs in spring which hatch in late summer. The offspring tent to create further "galleries" in the brickwork. It is advisable to re point in late summer if you spot any activity to prevent year on year degradation of the wall.
IT eats the humus rich soil through watch it burrows and some species also drag small pieces of plant matter down into their burrows and eat this. There are also species which predate other worms.
All species of wombats are herbivores and have a backwards facing pouch to protect its young whilst digging their burrows.The Burrowing bettong is also a pouched herbivore that burrows.
In a way. Rabbits are gregarious herbivores, live in burrows, and are noted for their high breeding rate.
Gopher tortoises dig burrows in areas where it is very hot in the summer and there is little shade. Other animals escape from the heat in these burrows. The burrows also provide shelter during cold nights in the winter, and a place for small animals to escape wildfires.
The burrowing owl makes its nest in the ground for breeding and nesting purposes. The owls will mate, and after the eggs are laid, the female incubates them while the male brings it food and guards the nest.
A homologous structure.
Keystone Species
Stoats and weasels will often take over burrows from their prey species, especially rabbits.
The limbs of Species A have a similar structure to the limbs of Species B, but perform a different function.
The number and structure of chromosomes help determine evolutionary relationships between species. Chromosome comparison helps to provide evidence of the relationships in a species.
