Disk-winged Bat vs Sucker-footed Bat
The disk-winged bat and sucker-footed bat are not closely related, yet both evolved strikingly similar adhesive pads for clinging inside a single rolled leaf, a textbook case of convergent evolution playing out on opposite sides of the world.

|---|---|---|
| Scientific name | Thyroptera tricolor | Myzopoda aurita |
| Adhesive structure | Suction-cup-like disks on wrists and ankles | Adhesive pads on wrists and ankles |
| Evolutionary origin | Evolved independently of the sucker-footed bat | Evolved independently of the disk-winged bat |
| Roost plant | A rolled young Heliconia leaf | A rolled young traveler's palm leaf |
| Roost stability | Must relocate every day or two as the leaf unfurls | Tied closely to a single, narrowly distributed host plant |
| Diet | Carnivore, catching flying insects | Carnivore, catching flying insects |
| Native range | Central and South America | Madagascar only |
| Conservation status | Least Concern | Near Threatened |
Disk-winged Bat vs Sucker-footed Bat: common questions
Are the disk-winged bat and sucker-footed bat closely related?
No, despite both having adhesive pads on their wrists and ankles, the two belong to entirely different, unrelated bat families; the similarity is a striking example of convergent evolution rather than shared ancestry.
Do the disk-winged bat and sucker-footed bat use the same host plant?
No, the disk-winged bat shelters inside a rolled Heliconia leaf in Central and South America, while the sucker-footed bat instead depends on the rolled leaves of the traveler's palm, a plant found only on Madagascar.
Which is more threatened, the disk-winged bat or the sucker-footed bat?
The sucker-footed bat, which is Near Threatened and restricted entirely to Madagascar, while the disk-winged bat remains Least Concern and widespread across Central and South America.
