Our jungle night hike in Costa Rica introduced us to the Owl Butterfly in addition to the tarantula, pit vipers, and scorpions we featured on that post. Some fun, huh. This owl butterfly photo was taken during the day at the Monteverde Butterfly Gardens, where we visited to see it, and other butterflies of Costa Rica, up close.
The owl butterfly is so named because the large spot on the lower part of the wing. It has a matching spot on the other wing that resemble an owl’s eyes when the wings are open and seen from below. It’s called mimicry. One theory is that predators see the eyes and decide that fleeing is a better option than chomping lest they end up being the chompee. Another theory is that the predator sees the eyes and thinks that they represent the head of the butterfly, bites down, and get a mouthful of wing instead of the body. Given that the owl butterfly is one of the giants of the butterfly world with a 6-8 inch wing span, it has plenty of wing left to still fly. Either theory leaves the butterfly free to complete its goal in life, which is to breed and have babies, i.e. lay eggs.
The eggs hatch into tiny caterpillars that come with a voracious appetite and quickly grow in size. Molting frequently, they change their looks each time. The caterpillar on the right is a younger version of the caterpillar on the left. The large hole in the banana leaf is why the big caterpillar is so big. It’s also the reason why banana farmers aren’t particularly fond of these insects that can grow 5 to 6 inches long off of devouring their plants before entering their chrysalis stage.From the perspective of the banana leaf, these owl caterpillars must look like one long gut approaching. The biggest one is about to enter the chrysalis stage of the metamorphous from caterpillar to butterfly. The first step is for to dissolve into a nutrient rich goop. Specialized cells that survive the melting process then utilize the nutrients to develop into the adult butterfly.The owl butterfly is quite beautiful when seen from above with its wings in open position. Here it was busy consuming watermelon that staff had left out for it. On the right is another one of Costa Rica’s best known butterflies, the blue morpho.Here a number of blue morpho are simultaneously hatching out of their chrysalis at a special hatching station that the Monteverde Butterfly Garden maintains for this purpose. Their wings have to dry and harden before they are ready to fly.Peggy found this blue morph chrysalis looking leaflike out in the Monteverde Butterfly Gardens. The chrysalis of the owl butterfly, btw, resembles the head of a viper. Both the leaf and the viper chrysalises are two more examples of evolutionary mimicry.A blue morph resting on leaves.A blue morpho gave us a brief glimpse of the vibrant blue color of its inner wing that gives the butterfly its name.
And now, for a quick look at some of the other beauties we photographed at the Monteverde Butterfly Gardens. Given that there are between 1200 and 1500 species of butterflies in Costa Rica, I’m late with this post, and my mind is on butterfly overload, I didn’t have time to pin down all the names.
Set off by green, a Green Longwing Butterfly. Great camouflage. One of a number of butterflies that pretend to be dead leaves. This may be excellent camouflage on leaf litter covered forest floor. Not so good here.Red spots. This may be a ‘see me, see me’ look as opposed to camouflage. The caterpillars of some butterflies feast on plants that are poisonous to birds, lizards and other predators. The poison is transferred to the butterfly. Instead of hiding, the butterfly, announces its presence with bright colors that are designed to tell predators ‘You really don’t want to eat me.’ Other butterflies may adopt the same colorization in what is known as Batesian mimicry. They aren’t poisonous, but who’s to know the difference?Lunch. Butterflies, unlike caterpillars, sip nectar with their long proboscis instead of eating leaves. This is a HeliconiusSara (I think.)This sulfur colored butterfly is using its proboscis to sip watermelon juice. Note the color of the proboscis. Many Costa Rican butterflies take advantage of fallen, rotting (translate fermenting) fruit for food. They can actually become a little tipsy.This one looks like the same species as above with its wings open.Brown on green.I call this a finger butterfly since it landed on Peggy’s finger and refused to get off. It may be a Crimson Longwing.I’m going with a Malachite Butterfly on this one.And this one as well even through the colors are dramatically different. But note how close the pattern of their spots is. The butterflies often rested on the screens that kept them in the butterfly houses. Maybe they were longing to be free.Peggy’s favorite, a Starry Night Cracker Butterfly.And a final beauty. This is a Variable Cracker Butterfly. The unusual cracker name is said to come from the noise they make when they are flying.As for what noise that is, I lifted this: “The Cracker butterfly gets its name because the males are able to produce a crackling sound, reminiscent of bacon cooking in a frying pan. They make the sound when they take off, by twanging a pair of spiny rods on their abdomen against their anal claspers.” Not sure about the anal clasper but it brings a vision to mind.
Next Post: It’s back to UT-OH with two more final tales about the Mekemson Gang. There’s the issue of how I lived up to Bertha Brays expectations about my leading her son astray (although there’s an issue of who led who.) And there’s a question about why Tony Pavy wanted to shoot me. It had to do with his pig.
