Goodness Snakes

Eastern Garter Snake

Eastern Garter Snake – non-venomous

Or, in the spirit of Eats, Shoots, and Leaves, Goodness! Snakes.  We call this little guy ‘Skimmer’ and he lives in and around our pond.  He’s an Eastern Garter snake and harmless to humans.

We’re well into spring and with warmer weather more snakes will be visible.  We think snakes are terrific and always feel lucky to see one in our yard or neighborhood.

Pantherophis alleghaniensis

Eastern Ratsnake – non-venomous

“Terrific? ” you say.  We say “yes”, because:

  • They are beautiful
  • Biologically they are fascinating since they move without limbs
  • They benefit our gardens by eating pests such as slugs, crickets, voles and rats
  • Snakes are food for others: hawks, owls, raccoons and other snakes

But some snakes can be dangerous so we consulted our friend and local snake expert, Robert Hill.  He gave us great information and permission to use some of his beautiful photos.

Here are some things to keep in mind:

    • There are approximately 30 species of snakes in and around Atlanta, only 4 of which are venomous and the rest are non-venomous.
    • The two harmless snakes most commonly misidentified as venomous in Peachtree Park are Dekay’s Brown Snake and Northern Watersnake.
  • In Peachtree Park , the only venomous snake we are likely to find is the Copperhead so it’s a good idea to learn to identify them.
  • Most bites result from attempts to catch, handle, kill or otherwise harass snakes.
  • Fewer than a dozen people in the entire United States die from snake bites each year.

See our Snakes page, which has more photos and information on snakes.  There are also additional references and a wonderful poster on venomous snakebites.

If you see a snake, be kind, and give him some room.

Ladybugs

Some call them ladybirds, lady beetles or ladybird beetles. We’ll stick with ladybugs, although the ladybug is not really a bug, but a beetle [1].

Most species of ladybugs are considered useful insects since they eat aphids and scale insects.  In other words, they provide organic pest control.   ‘A single lady beetle may eat as many as 5,000 aphids in its lifetime.’ [2].

LB Cycle 2

Ladybug Life Cycle

There are four phases to the ladybug’s life cycle:  eggs, larvae, pupa and adult.  It will take several weeks to go through the entire cycle.  Some species will have several generations each year while others have only one.

Ladybug Eggs

Ladybug Eggs

One ladybug can lay anywhere from 2 to 350 eggs [3].  This clutch has 28 eggs.

Emerging Ladybug Larva

Emerging Ladybug Larva

In the larval stage they look like little alligators and are voracious aphid eaters. Once hatched, the larvae eat about 350 to 400 aphids in the 2 weeks it takes them to become fully grown [3] .  They go through 3 or 4 cycles of shedding their skin before entering the pupa stage.  Each iteration is called an instar [4].

LB - Pupa

Ladybug Pupa

The larva will attach itself to a leaf or twig and transition to the pupa stage.   It will remain in pupa form for 2 to 3 days before emerging as fully formed ladybug.

Ladybug New Adult

A ladybug that has just emerged

The newly hatched ladybug will have no spots for the first few hours and will will open and close their wings to dry them.  Slowly the spots will appear.

The short movie below shows the full cycle.
