Its members are primarily found in Australasia and temperate South America,[3] and include the most common native bees in New Zealand.

However, they multible species in New Zealand have been recorded visiting kiwifruit flowers,[6][8] and agricultural studies have caught them in clover pastures and orchards.

[13][14] Lots of these species live in dry woodlands on acidic sandy soils that are suited to Leioproctus as they are mining bees and can tolerate these harsh environments.

[15] Research has gone into using native bees for commercial pollination and found positive results and successful trials of nest removal and re-establishment.

[16] Because they nest individually, they would be more resistant to spread of disease, like Varroa mites or AFB, which is of increasing interest in agriculture.

Because domestic honeybees live in mobile hives, beekeepers can move these hives into high resource areas and then remove them once the nectar and pollen are depleted, forcing the sessile leioproctus bees to travel far distances to find resources.

This can range from forest undergrowth to roadside ditches to sandy costal banks to even currently occupied termite nests in at least one Australian species.

[20] This tolerance to wet conditions has been observed in multiple studies where as long as it was reasonably warm, bees would be seen, no matter the rainfall.

[18] Leioproctus overwinters as diapausing prepupae in cells before they pupate and begin appearing in spring or early summer.

After the eggs are laid, the larvae hatch around 72 hours later and consume all stored food over the next 10 days, then over the next few weeks become prepupae and diapause until the following spring.

In New Zealand and Australia Leioproctus feed primarily on species within Family Proteaceae, Fabaceae and Myrtaceae.
