Chameleon

A routine trip to Nandi Hills in April bore unexpected results in the form our first ever Chameleon sighting!

Due to the overcast weather which looked like rain, we decided to leave late and took a detour to the Hoysala Bhoganandishwara Temple ( a post on this soon, I promise) before going up to Nandi Hills for lunch in their Mayura Restaurant.

Enroute to the temple, we were at a decent speed on empty roads when Keshav suddenly yelled "Stop Stop"! I thought it was a snake he had spotted, I had barely stopped that he was out like a rocket and running back down the road, camera in hand.

A few minutes later, I had parked, recovered my senses, got my camera from the boot, and walked back round the bend to find him prostrate in the presence of the cutest little critter ever! Our first Chameleon!

Not to be confused with a common Garden Lizard, or a Rock Agama, a chameleon is a totally different reptile all together.

Chamaeleo Zeylanicus is commonly known as the Indian Chameleon. There is only one species of chameleon in India. They are common in Africa and Madagascar, spread over Europe and parts of Asia. They have been introduced to North America.

Chameleon Common Facts:

1. They move slowly, almost in slow motion, and in a very hesitant, unsteady way.
2. They have a long tongue having a sticky end, which serves to catch prey that they would otherwise never be able to reach with their lack of speed.
3. They can move their eyes independently of each other. Having one looking ahead while the other looks behind. This gives a full 360 degree of view.
4. They hear vibrations in the air, which help them find food and stay safe from their enemies. They are almost deaf - they have no external ear.
5. They have 5 digits on each foot. But they are grouped as 3 and 2. Two opposing digits gives a better grip. The digit grouping is reversed in the rear feet.
6. They are cold blooded and need the sun to regulate body temperature.
7. They have small teeth. They eat mainly insects and larger species eat small birds and reptiles.
8. They lay eggs in a hole in the ground. Some species (ovoviviparous species) give birth to live young.
9. They are non-venomous. But if you are bitten by one, there is chance of infection.
10. They have a prehensile tail, they are the only lizards which have such a tail.

Colorful Ideas

They change color according to their background for camouflage - Wrong! (Personally I was surprised too )

They change color according to emotions - Excitement and fright produce pale shades with brown patches and yellow spots. Anger causes darkening.

They also use color change to regulate their body temperature. Dark colors absorb heat better, so the side of the chameleon facing the sun becomes darker, while the other side remains its usual color.

It is also believed that they can communicate with other chameleons using color. During the mating season (in India around October) they turn their skin bright green while during fights they turn Dark brown. The Indian Chameleon is normally grey-green, but in total darkness this fades to a cream color with irregular yellow spots.

They can however change color for camouflage as well, but only in a limited way.
They aren't the only ones, several other species of lizard have that ability too.

Chameleons and other indian reptiles do not shoot blood out of their eyes - this property is that of the Horned Lizard (North American) which shoots blood into the eyes of foxes and coyotes ( which the predators find foul tasting ).

Getting Close

While we wanted to avoid doing an Austin Stevens on our little friend, we did have to get a little close due to the choice of lens ( I had a 50mm f1.8) we each had on our cameras. Our little guy was so small and cute, the urge to touch was very great, but we valiantly resisted.

I'm happy to report that our little critter was mostly unconcerned by our presence based on the research Ive been doing. When upset, chameleons change color rapidly and if one gets too close, it makes a "Haaaaa" hissing noise similar to a snake.
We did not get either of the reactions, so I think we did well.

So what should you do when you encounter a chameleon? You'd want to keep it safe out of harms way, help it cross the road and see it safely into a nearby bush. Handle it gently and treat it kindly.

Its a Boy!

Distinguishing male from female is not easy. The indian male (chameleon) has a spur on the rear feet to identify it as one. Based on this info, I have concluded that our little guy is a Guy! Experts feel free to point out any mistakes.

Lady Bird Beetle

Long time since a post from me, isn't it? I'm back though and staring with ever increasing fear as the tidal wave of unprocessed images rises up on me. People, I'm dealing with a backlog stretching as far back as Dec 2010.

But first, to more recent images; this one is a first for this blog - a Critter post. Presenting the world's favorite beetle - The LadyBird. We had a few visitors last week which I found among the sofa cushions in the morning. The resulting impromptu photo-shoot made Keshav and I late for work.

A little research to Id my new friends ( they are living in one of my plants now ) led to a wealth of such astonishing information, that I just had to write a post and share it with all who are willing to listen.

Some weird trivia that you never knew about LadyBirds:

Warning: If you are not 18 and above, read no further :)

1. They are perhaps the only species on earth whose male individuals are capable of ejaculating on average 2–3 times per copulation.
2. They can copulate for 9 hours straight, experiencing several orgasms, each lasting up to 30 minutes!
3. ladybirds also sadly suffer from an STD epidemic caused by a parasite

So, now that I've got your attention, we can move on to more mundane info.

The Name - is it ladybird or ladybug?


As it turns out, its actually the Lady Beetle or Ladybird beetle. Because ladybirds are not "true bugs" or Hemiptera. ( To learn more about Hemiptera click here )

They are Coccinellidae. The name originates from Britain ( for the Seven Spot Lady Bird ) called Our Lady's Bird, because of depictions of Mary the mother of Christ wearing a Red Cloak. The Seven spots representing her "seven joys and sorrows".

Aphid Hunter

Most Ladybirds are beneficial insects ( i.e beneficial to humans, gardeners and farmers ), they are natural predators of the dreaded aphids. My new friends have been made allies in my long running war with my balcony's aphid population.

My ladybirds seem to be : Coccinella transversalis Fabricius
or the Transverse Ladybird.

They are active July - November in South India. I suspect their early arrival coincides with the daily rains we have been having lately. For some details you can visit aphidweb.

Diet

A normal ladybird diet consists of "pest" insects and their eggs, mildew and pollen.
They have also been known (rarely) to resort to cannibalism.
Like humans, ladybirds are active during the day and go to sleep at night.

Self Defense

1. The bright colour ( red, orange and yellow ) is a sure giveaway; indicating to most predators that ladybirds are not good to eat.
2. They can play dead - I've seen this just once a few days ago when I encountered a ladybird which I collected as our maid was sweeping. It seemed dead at the time, I moved it to a pot in the balcony and checking back an hour later, it was up and about!
3. Smell and taste - they secrete a foul tasting/smelling fluid - Im happy to say Ive not encountered it yet.
4. They have mandibles - i.e they can bite.

Ive found them quite willing to be friends, moving them from the sofa to a pot outside required a dried periwinkle leaf as transport and very little persuasion.

Basic Anatomy

We aren't going into details here, but the most important word here is elytra. That's the hard colored and spotted shell of the ladybird. It conceals the wings beneath which are fully see-through.

The Pronotum - this is the cover that protects the head of the ladybird, it is capable of retracting its head under this cover like a turtle.
Like all insects they have six legs, but their legs have organs which can smell!

Lifecycle

They are quick little critters when it comes to growing up. From egg laying, it takes them just 5 days to hatch into larvae. In the larval stage they are as ugly as ugly can get, but be patient. Larva eat aphids too, so they may be ugly but they still do the job. 2-3 weeks and many aphid dinners later, they are ready to pupate into their cute adult forms.

Being a good Host

Ok, so they are cute, friendly and useful; not to mention photogenic. How can you get more of them?

They are attracted to Marigolds ( this is easy to get hold of in India, and grows like a weed ), Cosmos, Mustard and Dill. Plant them and wait for the rainy season.

FYI: I have a small collection of baby marigolds currently flowering. I'm planning to plant cosmos soon, once I get hold of an empty pot.

In-case you were wondering, LadyBirds can live for 2-3 years.


Aside:

Yes! we have acquired new lenses! Keshav's macro lens is taking some getting used to. Handheld is impossible and its pretty heavy too. A little 50mm for me will be showcased in the next critter post shortly!
