Welcome to the Butterfly Shelf of the Fauna Room.
Butterflies of the Florida Keys

Butterfly Gardening is Encouraged. 

     Adult butterflies can be found all months in the Keys with February the least; however, the ranges of species vary only from about 54 to 72.  Five families of butterflies regularly appear in the Keys. They are the Papilionidae (Swallowtails), Nymphalidae (Brush-footed), Hesperiidae (Skippers), Pieridae (Whites and Suphurs) and  Lycaenidae (Hairstreaks and Blues). In their book Butterflies of the Florida Keys, Marc Minno and Thomas Emmel show color plates of 106 species reported in the Florida Keys. The loss of and threatened habitat is considered the most critical. Both host and food plants will be necessary for survival. Aerial spraying for mosquito control is considered problematic and new insecticides are being studied. -------------------- 
-Family Papilionidae-
   

  Swallowtails are probably the best known of North American butterflies and are of the family Papilionidae, but are found throughout the world. Their colors are quite variable and range from almost yellow to almost black.  -
   

  The Schaus' is one of the seven listed as endangered of the 573 Swallowtail Butterflies species worldwide. Originally an occupant of the entire Upper Keys, their numbers are down to somewhere in the low 100s now. In 1911, William Schaus collected specimens in the Miami area. Loss of habitat and pesticides are attributed to their decline. They lay their eggs in the torchwood and wild lime trees on North Key Largo. Only a few contemporary people have actually seen the Schaus'.
     Other Papilionidae seen the Keys have been: Polydamous, Cuban Kite, Bahama, Giant and Palamedes.  ----------------------------
- Family Nymphalidae -

-      The Monarch is of the Milkweed Butterflies of the family Nymphalidae and is one of the two species found in North America. It may be the best known butterfly and is noted for its migrations. Allegedly, they have a disagreeable taste to birds and this may account for their great numbers. -

     Another of the family Nymphalidae is its cousin shown above, the Queen Butterfly, resembles the Monarch but is smaller, darker and not as brilliant. Butterflies are cold blooded animals. Beetles are the only other insect that have more species than the butterfly.
-
    

 The Zebra Longwing of the family Nymphalidae is the Florida State official butterfly and the adult is shown above. This zebra has a rather short life span; therefore its color variations can be many in a year's time. It can be seen in the Florida Keys but is more popular in the Everglades. -
     

 Butterflies are vociferous eaters, molts its skin about five times before it pupates. -

 The Heliconians are a subfamily of the Nymphalidae, the passion flower butterflies. The Gulf Fritillary larvae feeds on the passion flower which is found in the Florida Keys. The adult feeds on lantana, thistle and passionflower and has a life span of about one month. Some of the various stages of the Gulf Fritillary's life is shown below.  -

  The above young fritillary has just emerged from its pupae and is drying its wings. It flew away about 10 minutes after the above photo was taken. Note the different coloration of the undersides of the wings. Most butterflies have different color patterns on each side of its wings. The usually brighter patterns are on the top and is used to attract an mate. The underside is duller and better serves as a camouflage; therefore it usually sits with its wings folded. -

 An idea of the growth of the fritillary from its egg to caterpillar. Butterflies normally deposit their eggs on a specific plant; therefore, destruction of fauna can be fatal to butterflies. In the Keys the plant is passion flower (preferably the P. suberosa) which is one of the three native passion flowers. -

 Two pupa suspended from an electric cord just above the passion flower shown above.
     About 30 other Nymphalidae butterflies in five subfamilies have been seen and photographed in the Keys. Some are Red Admiral, Banded Orange, Black Mangrove, Common Buckeye, Cuban Peacock, Cuban Crescent,  White Peacock, Julia, Florida Purple Wing, and Ruddy Dagger Wing. --------------------
- Family Peridae -

     Of the family Peridae the Florida White shown above and the Great Southern White are frequently seen in all the Keys. The Florida White are mostly seen hammock areas and the Great Southern White in marshy areas. -

 The Large Orange Sulphur are mostly found in southern Florida. The caterpillar prefers cats claw and wild tamarind which are found abundantly in the Keys. The adult feed on a large variety of flowers. -

The Sleepy Orange is seldom seen in wooded areas and appears to prefer scarified and weedy areas. For some reason they are not seen as often in the Upper Keys, presumably because of the lack of host plants. They are mostly a summer butterfly in the Keys.
      At least 30 other Pieridae have been photographed in the Keys of which some are: Giant Brimstone (rare), Checkered White, Jamaican Sulphur, Barred Sulphur, Cloudless Sulphur and Orange Barred Sulphur. -------------------------
- Family Lycaenidae -

   Family Lycaenidae (Gossamer wings). The larvae of the Gray Hairstreak shown above is not as picky eater as some but in the Keys the hibiscus is a good food source. The adult can usually find milkweed in the Keys, but many other foods are consumed on the mainland. It is found throughout the U.S. -

 Another Lycaenidae is Bartram's Hairstreak named after William Bartram who in the early 1700s explored Florida. It was once thought threatened but appears to be replenishing. In the Keys it is found mostly in the pinelands of the lower Keys.
     Not many of the Lycaenidae are easily found in the Keys. The Cuban Gray, Modest Hairstreak, Miami Blue and Cassius Blue are perhaps the easiest.  The Ceraunus Blue, Eastern Pigmy Blue, Light Banded Hairstreak, Disguised Hairstreak and Atala Hairstreak are more difficult. ---------------------------
- Family Hesperiidae -

  Another of the family Hesperiidae, the Tropical Checkered Skipper is shown  above. Larvae feed on the hibiscus and mallow plants. They fly low in weedy and disturbed areas. The females are darker than the males.  -

 The caterpillar of the Mangrove Skipper feeds on the leaves of the red mangrove. The female is not as brightly colored and as most butterflies, she lays her eggs on the same plant that the larvae will  need for food. The Mangrove skipper can be confused with a moth as it has a furry type body. 
     One of the larger families, mainly in two subfamilies,  found in the Keys is the Hesperiidae.  The Long Tailed, Dorantes, Hammock, Zestos and Zarucco Dusty Wing are some of the Skippers. Of the Branded Wing Skippers, the Field, Fiery, Eufala, Monk, Broken Dash and Obscure are perhaps  the most common found. ---------------END----------------
