Orion Cecropian Historis odious Photo by Tino Sánchez This captivating, large butterfly has a wingspan of 11 cm (4 in.) and calls attention with its bright orange upperparts when flying. However, at rest, they fold their wings up, revealing their leaf-like brown underside, even showing a vertical line reminiscent of the vein of a leaf, providing excellent camouflage. They are very closely associated with cecropia trees—from laying their eggs on its leaves to perching high on its branches, all life stages of this species associates with cecropia trees. From the treetops, it flies down to the ground to feed on fermenting forest fruits, earning this species its nickname, the “Stinky Leafwing.” Males are attracted to rocky overhangs, riverbanks and muddy wallows to pick up dissolved minerals in the water. Keep an eye out for this common butterfly at eye level from the Observation Deck of the Canopy Tower, and at the fruit feeders at the Canopy Lodge and Canopy Camp. Strange defenses: The larval caterpillars produce frass-chains, which they dangle off the edges of cecropia leaves where they are resting to avoid being eaten by the resident Azteca ants.

Blue-winged Helicopter Damselfly Megaloprepus caerulatus Photo by Domiciano Alveo With a wingspan of up to 19 cm, the Blue-winged Helicopter is the largest member of the dragonfly and damselfly order, Odonata. It is large, with a body length up to 13 cm, and slender. In addition to their large size, Blue-winged Helicopter damselflies have dark brown to black bodies with yellowish markings, and transparent wings with a dark blue band on the outer third near the wing tip. Males are distinguished by having a thick white band on the wings inside the blue band. Females lack this white band, but have a creamy white spot at each wing tip. Males are larger than females, which is unusual among dragonflies and damselflies. The Blue-winged Helicopter damsel is the only member of the genus Megaloprepus. The Blue-winged Helicopter damselfly is a member of the family Pseudostigmatidae, the helicopter damsels and forest giant damsels. They are called helicopter damselflies because their four wings beat independently, and appear to whirl around like the blades of a helicopter. Helicopter damselflies are only found in tropical regions, and require environments with plenty of rainfall – rainforests are their ideal home. This species is the most spectacular of Panama’s 6 species of helicopter damselflies. Blue-winged Helicopter damselflies are found in the understorey of tropical rainforests. They do not emerge to cross large clearings, and have poor flight endurance, resting often by perching on a leaf or twig with its abdomen hanging downward. They are most common in mature, old-growth forests and are not commonly found in secondary growth. Adult Blue-winged Helicopter damsels specialize in plucking spiders from their webs while in flight using their long legs. They prefer small, soft-bellied spiders that are easier to eat. Blue-winged Helicopter damsels breed in phytotelmata – small pools of water

Rusted Clearwing-Satyr Cithaerias pireta Photo by Jenn Sinasac Also known as “Pink-tipped Satyr” and “Blushing Phantom”, this pretty, delicate butterfly is a member of the Nymphalidae family, the brushfoots. It is one of the many striking, beautiful butterflies of tropical America, ranging from Guatemala, throughout Central America and into South America. Its clear wings lack scales, revealing the transparent wing membranes, highlighted with iridescent bright pink on the hindwings and an ocellus or “false eye”. It rests with its wings folded, raising its hind wings perhaps to resemble a small snake, deterring lizards or birds from eating it. This solitary, crepuscular butterfly flies primarily at dawn and dusk, close to the ground in deep, shady rainforest and cloud forest. It has a slow and bounding flight pattern. It rests often on the ground or low vegetation, but is easily disturbed and capable of moving fast to evade predation. Rusted Clearwing-Satyrs feed on rotting palm fruits and fluids from decomposing fungi. In Panama, they are found most commonly in the foothills up to 2000 meters in elevation, and are fairly common around the Canopy Lodge; they can also be seen in the lowland rainforests around the Canopy Tower and Canopy Camp Darien.

Red Cracker Hamadryas amphinome Photo by Jenn Sinasac The Red Cracker is a truly flashy butterfly! Among some very interesting behaviors, the Red Cracker butterfly is strikingly beautiful – bright metallic blue and black calico coloration on the upperside, bold white stripe across its forewings, complimented by fiery red-orange on the underside of the hindwing. Males and females are similar. It is a medium-sized brushfoot butterfly (family Nymphalidae) with a wingspan of 7.4-8.6 cm. Red Crackers rest head down on a tree trunk, often high up (10+ meters), with wings spread flat against the bark. While the calico pattern on the wings of some cracker species allows for camouflage with tree bark, the Red Cracker’s bright colors allow it to stand out and they are rather easy to spot. They descend to the ground to feed on rotting fruit, and will visit platform feeders. The female Red Cracker butterfly lays tiny white eggs in a chain up to a dozen eggs, hanging on the underside of a leaf. Larvae are black with yellow mottling on their back, covered in branching black and orange spines. Larvae feed gregariously on their host plant, Dalechampia scandens (Euphorbiaceae) and live communally. The Hamadryas amphinome chrysalis appears as a dried, withering leaf. The Red 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. Both males and females can detect the sound produced by the males, using tiny, hollow cells covered by membranes on their wings. As they vibrate, they stimulate nerve endings. It is thought that males produce this crackling sound as a territorial defense against other males, or

Giant Butterfly-Moth Castniomera atymnius Photo by Jenn Sinasac The Giant Butterfly-Moth is one of the most intriguing of Panama's insects. This diurnal moth creates much confusion when it comes to identification—it is easily confused with butterflies, as it flies during the day and even has clubbed antennae! At close glance, the robust body is an indication you are looking at a moth. This conspicuous, fairly large (wingspan 10 cm), daytime-flying moth is medium to dark brown in coloration with pale whitish lines on forewings. On the hindwings, a white, heart-shaped marking is often covered by resting folded forewings. Castniomera atymnius can be found commonly in the lowlands and foothills, where its larvae feed on Musaceae species. Castniomera atymnius is the only species in the genus Castniomera, and is comprised of several subspecies throughout its wide distribution from Mexico to Brazil. Keep an eye out for these bold moths around all the Canopy Family lodges. The family Castniidae (Giant Butterfly-Moths) is a small family containing approximately 170 species. Castniid moths are generally medium to large in size, having drab forewings with brightly-colored hindwings. They are found mainly in the Neotropics, but also have representative species from Australia and southeast Asia, where they are known as “Sun Moths.”

Rothschild's Giant Silkmoth Rothschildia triloba Photo by Jenn Sinasac Rothschild’s Giant Silkmoths are among the largest and most beautiful of all moths. With a wide wingspan of 10-12 cm, they are approximately the size of a salad plate! Adult moths in the genus are distinguished by their large size, with transparent, triangular windows in each wing. Even as flashy, beautiful moths, they have various characteristics to assist with camouflage. The windows in the wings allow light to pass through, breaking up the wing profile and helping the moth avoid predation. Their wings also somewhat resemble a dry, decaying leaf with their cryptic patterns. Females have more rounded wings than males. Adults do not feed—after mating and laying eggs, their life's function is fulfilled. Rothschildia triloba is a rainforest canopy species, found in the lowlands and foothills from sea level up to 1400 meters. It is found in middle and upper levels of the forest. It is more reddish and larger than other species in the genus found within the same range. It is widely adapted and can be found in a wide variety of habitats. Caterpillars are large and green with some countershading. They are difficult to find since they feed on a wide range of low-density species as host plants, including members of the families Anacardiaceae, Bursuraceae, Euphorbiaceae, Moraceae, Rosaceae, Rubiaceae, Saliaceae and many others. Larvae spin a dense pendant cocoon firmly bound to a twig with a long silk extension. Cocoons are sloppy in appearance, resembling a messy cluster of dead leaves, and are placed low in the understory of the forest, often just 1-2 meters above the ground to avoid predation by monkeys and birds. When the adults emerge from the cocoons, they seek out and mate that same night. Adults are found at very low density

Giant Ceiba Borer Euchroma gigantea Photo by Jenn Sinasac This very distinctive beetle always captivates our guests—it’s one of the largest beetles around! In addition to its whopping size (5-8 cm), its robust, elongated body and hard elytra (outer wings) are an attractive metallic green with purplish and reddish tinges; however, often this shiny exterior is covered with a yellowish waxy powder coating, most prevalent on newly emerged adults, and wearing off as the beetle ages. Its pronotum (prothorax) has two distinct large black spots. This species has large eyes and segmented antennae. The larvae of the Giant Ceiba Borer are huge—the 12-15 cm grub which bores through fallen timber, feeding on decaying wood mostly of the Bombaceae family (softwood species including Ceiba, Pseudobombax and Ochroma), but also on Ficus species. They have a special gut bacteria that breaks down cellulose and helps digest wood. Adults are typically found walking around on the surface of tree trunks and thick branches, and they feed on leaves and pollen, frequently visiting flowers. They are diurnal, spending time sunning themselves on trees, and move slowly unless alarmed. Giant Ceiba Borers typically breed and lay eggs in August. Males produce a clicking sound with their elytra to attract females. Females lay eggs on decomposing logs, eggs are laid in four groups of 10 eggs on one stump, and the female will lay up to 240 eggs throughout her lifetime. Grubs take up to 2 years to develop, and receive no parental care. Giant Ceiba Borers are one of the largest members of the family Buprestidae (the metallic wood-boring beetles) and the only member of the genus Euchroma. Members of this family are notorious for damaging trees, and this species can possibly cause sufficient tree damage by eating the roots to cause the tree to

Harlequin Beetle Acrocinus longimanus Photo by Jenn Sinasac One of the largest and most beautiful beetles of the Neotropics, the Harlequin Beetle is named for the ornate, colorful red, olive & black pattern on the elytra (hardened wings) of both the male and female. This beetle is a member of the longhorn beetle family, Cerambycidae; members of this family have long antennae, often longer than the length of their body! Adults have a body length of close to 8 cm, and males are particularly impressive because they have elongated forelegs, extending much longer than the length of their body. Harlequin Beetles are found from Mexico to Brazil; they can be found on the bark of trees on which they feed on sap and lay eggs. This male was spotted at the Canopy B&B in Gamboa.

Great Eurybia Eurybia patrona persona Photo by Jenn Sinasac Also known as the Great Sheenmark, this is a large, recognizable member of the metalmark family, Riodinidae. At 30-35 mm, it is the largest of its genus in Panama. The Great Eurybia is distinguished by its large size and reddish hind wings. It has a reflective “eye” on each forewing, glowing iridescent blue, even in the dark forest understory. The “eyes” of males are much larger than those of females. The proboscis is very long—typically 1.5 times the length of its body—allowing it to access nectar deep in long flower corollas. This is an unusual characteristic, and is the longest of any butterfly. Eggs are flattened, lozenge-shaped, and pale-green, turning white after a few days. Eggs are laid on stems, flowers or the base of the host plant. Maggot-like larvae are yellow with two brown patches on the thorax and have a dark brown head. They feed on the host plant flowers. Caterpillars secrete nectar from tentacle nectary organs to feed attending ants. Caterpillars are parasitized by wasps (Braconidae: Rogas spp.). The pupae are pale brown and are often near a temporary ant colony. The sheath enclosing the pupa may extend a full body length past the last abdominal segment. Great Eurybias can be found perching on the undersides of large leaves. This is thought to be a preferred way to “launch” into flight. They have fast, erratic flight, and are usually solitary. They exhibit lek-like activity along natural boundaries such as streams and trails. Males fly in long sweeping loops around a host plant stand, often remaining airborne for several minutes. This is both for courtship display and territory defense. The Great Eurybia is found in the forest understory and feeds on Calathea spp. (host plant), Crimson Passion Flower, Heliconia,

Regal Hairstreak Evenus regalis Photo by Jenn Sinasac From the observation deck of the Canopy Tower, you may be fortunate to see one of the most stunning butterflies of the Neotropics, the Regal Hairstreak. This flashy member of the family Lycaenidae is distinguished by its iridescent green and blue coloration. The dorsal side (upperside) is a brilliant blue with a thin black border on males, less blue on females. Both sexes have a protruding red spot at the end of the hindwing on the upperside where the long tails trail off. The ventral side (underside) is iridescent green with a thin vertical black stripe and a wide vertical red stripe on its hindwings. Males are marginally smaller than females, and have a brilliant white abdomen. Like most hairstreaks, the Regal Hairstreak has long, wispy tails that appear like a false head and antennae to distract predators away from its head. Larvae are plump and globular in shape, with a cinched “waist.” The caterpillar is green with brown markings in the first few instars, changing to brown and black tones in the later instars, where it reaches a size of 19 mm. Its head is concealed under its globular body. The caterpillar has very good camouflage, and blends in nicely with dried leaves or small branches. The pupa is round, brown and formed on a branch or leaf, and is 15 mm in length. The pupa stage is 14-18 days. Regal Hairstreaks reproduce from June to December, during Panama’s green season. The Regal Hairstreak’s larval foodplant is Manilkara chicle (family Sapotaceae) in Central America. Adult butterflies around the Canopy Tower are seen perching on Guacimo Colorado (Leuhea seemannii) and Harino (Enterolobium schomburgkii) trees; they are often seen flying for brief moments, flashing their blue uppersides, then resting on leaves for often
