What the Heck is a Hairstreak?

It’s a Bird, It’s a Plane, It’s a Butterfly!

What the heck is a Hairstreak? Ok, ok, I know it is a butterfly and a fairly common one to be sure but where did it get its rather curious and comical name?

The Hairstreak... an unassuming Superhero?

Is the Hairstreak just another unassuming Superhero who is to inspire the names of scads of amusement park coasters?

Hmmm… I don’t think so, but I do believe that Hairstreaks somewhat fit the Superhero bill. They are, after all, courageous and dashing creatures who fly about in uniquely patterned suits.

The dictionary defines the word Hairstreak as being small butterflies of the family Lycaenidae (Subfamily Theclinae) which usually have striped markings on the underside of their wings and thin filamentous projections from the hind wings.

Jeff Glassberg, author of Butterflies Through Binoculars, has this to say about origins of the word Hairstreak.  ”The name of these small but intricately patterned butterflies is thought to be derived either from the many lines or streaks that tend to appear on the hind wing or from the usual presence of fine, hair-like tails.”

Having observed these dazzling creatures in action, I can personally attest to accuracy of the above descriptions. Hairstreaks often have brightly streaked markings. They also flaunt false antennae or hairlike tails which are meant to confuse predators as to which side is their actual head is on.

In truth though, I have to wonder if anybody really knows for sure where the name Hairstreak originated from. Inarguably, Hairstreaks are hairy little daredevils who streak by in flashes of color. Telltale markings and counterfeit antennae aside, I myself, admittedly incurably romantic, will always prefer to think of them as mild mannered Superheros. -K. D’Angelo

Giant Swallowtail Butterfly vs Citrus Leafminer Moths

Giant Swallowtail Butterfly

Giant Swallowtail Butterfly

The Giant Swallowtail Butterfly (Papilio cresphontes) lay their eggs on the tender young leaves of many types of citrus, including Orange, Lemon, Grapefruit and Kumquat. The Giant Swallowtail Caterpillars feeds on the leaves of the citrus tree until pupating and emerging as one of the North America’s largest butterflies.

Damaged Citrus Leaves due to the Citrus Leafminer

In the last several years the influx of the Citrus Leafminer has left little food for the larva of these large graceful butterflies. The Citrus Leafminer (Phyllocnistis citrella) also lays it’s egss on citrus.  The Citrus Leafminer is a very small, light colored moth. Their newly emerged larvae immediately begin feeding on the leaves and “mine” themselves inside the top or bottom layer of the citrus leaf, causing the leaves to curl and harden making them inedible for the caterpillar of the Giant Swallowtail Butterfly.

Please don’t spray citrus trees with insecticides, instead use Blue Sticky Traps or Citrus Leafminer Pheromone Traps which attract the male citrus Leafminer and help to reduce the population and reproduction of these pests.

Protect the tender new growth of your citrus tree for the Giant Swallowtail Butterfly and help create a friendlier environment for the these lovely butterflies!

Learning about Lepidoptera

Everybody loves to learn about lepidopetera and Kristen enjoys teaching people about them. “Educating others about butterflies is so rewarding! Butterflies are fascinating and fun to learn about and having an understanding of their life cycle also helps to raise awareness of the delicate balance of nature.”

Caterpillar Camouflage Revealed

Peek-a-boo…  I see you!

? caterpillar

I know I resemble a snake or a manatee but can you guess who I really am? Do you know exactly what species I will turn out to be. Leave a comment with your best guess, but hurry I will be revealing my true identity soon!

I am starting to change… Do you recognize me still? I am a different color now but have the same melancholy lavender eyespots. I have turned brown because I am no longer grazing and resting upon green leaves. Now I am a stealthy climber looking for a place to safely switch my identity. I don’t want anybody to see me as I move about the dark colored branches.

Ok, I am guessing you may really have a hard time knowing me now. I have not only lost my lavender eyes but my legs too. Scary Looking Tree Bark is my new look, quite the trend in the Chrysalis World and camouflaging too! Hope you like it and if you think this is cool just wait until you see what I do next!

Pale Swallowtail

Oh, there’s a bit of chill in the air now and the days have grown shorter! I have a feeling if I emerge from my chrysalis at this time I won’t have any friends to flutter with. Think I will stay as I am over winter, patiently waiting, resting  inside my cozy shelter.

I will dream of the suns warm rays gently awakening me from my slumber. I can feel the winds raising me up to dance with the heavens. Upon bright wings, gracefully I will soar, adorning skies and embracing sweet flowers.  I am boundless and free as a Butterfly.

Look to the skies and watch for me and my friends, we will be in flight come springtime.
