Black Mastiff Bat (Molossus rufus)
During our last night tour, we had an outstanding encounter, the insectivorous bat called Black Mastiff Bat (Molossus rufus) in the family Molossidae.
They have long, thin wings that allow them to fly fast for long periods, however these wings do not work well at low speeds, therefore they must drop from a perch in order to take off. In this sense these bats are much like swifts and albatrosses.
Some species in this family has being recorded reaching speeds of more than 100 km/h (60 mph). They catch their prey above the canopy or in open areas with great precision.
Molossus bats play a crucial rolein controllinginsect populations, making them ecologically important in their respective ecosystems.
these bats are social animals, often forming colonies with varying sizes depending on the species. During the day they rest in roosts, which can include caves, tunnels and buildings.
This bat was spotted by my nephew Cris.

Impressive Snake Mimicry
Hemeroplanes caterpillars, native to Central and South America, include two species found in Costa Rica: Hemeroplanes triptolemus and Hemeroplanes ornatus. These members of the Sphingidae family, or hawk moths, are renowned for their extraordinary snake mimicry. When threatened, they rear up and expose false eyespots, convincingly imitating a striking snake to deter predators.
Their feeding habits are equally fascinating. These herbivorous caterpillars primarily consume leaves from plants in two families: Apocynaceae (Mesechites trifida, Fischeria panamensis, Mandevilla hirsuta, Mandevilla subsagittata, and Prestonia cuadrangulares) and Asclepiadaceae (Tassadia obovata). They prefer to feed along leaf edges, a strategy that minimizes visible damage and helps them avoid detection by predators.
This behavior is particularly advantageous in Costa Rica's biodiverse ecosystems, where predation pressure is high. Their snake mimicry is a striking example of Batesian mimicry, blending visual deception with behavioral adaptations. This unique survival strategy offers valuable insights into evolutionary biology and the dynamic relationships between predators and prey.
