It is similar to other hammer orchids in that it is pollinated by a single species of male thynnid wasp using sexual deception.

Drakaea micrantha is similar to others in the genus in that it has a single, ground hugging leaf and an underground tuber.

[1] The dwarf hammer orchid occurs at Perth, Augusta and Porongurup National Park[1] It grows in bare sand in woodland, often near Kunzea glabrescens thickets.

[6][7] The Western Australian Government Department of Parks and Wildlife classifies the species as "threatened"[5] meaning that it is considered likely to become extinct, or rare and in need of special protection.

The main threat to the species' survival is fire during its growing and flowering stages between June and early October.
