Ecology and Behavior:
A resident of desert-scrub country, the Lesser Long-nosed Bat is colonial,
occupying mines and caves at the base of mountains where the alluvial
fan supports agaves, yuccas, saguaros, and organ pipe cacti. It hangs
with its feet so close together it can turn nearly 360° to watch
for predators. Like other leaf-nosed bats, it takes flight when disturbed.
When launching, it gives several strong wing beats, bringing the body
into a horizontal position before releasing its grip. It is an agile
flier and can fly nearly straight up while maintaining a horizontal
body position. Flight is rapid and direct, but the bats can hover momentarily
and maneuver well. It emerges within about one hour after sundown. The
long tongue, covered with hair-like papillae toward the tip, is well
adapted for feeding at flowers. These bats may land on the flowering
stalk of agaves and insert their long snouts into each blossom. After
feeding, the stomach is so distended the bat appears to be in late pregnancy.
When the stomach is filled, they retire to a night roost where they
hang and rest. .
Nectar, pollen, and insects are consumed, but fruits are eaten after
the flowering season is past.
Reproduction and Longevity:
One baby is born in late May or June. Maternity colonies may harbor
thousands of individuals.
