Caterpillars are the larval form of a member of the order Lepidoptera (the insect order comprising butterflies and moths). They are mostly phytophagous in food habit, with some species being entomophagous. Caterpillars are voracious feeders and many of them are considered pests in agriculture. Many moth species are better known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce.

The etymological origins of the word are from the early 1500s, from Middle English catirpel, catirpeller, probably an alteration of Old North French catepelose : cate, cat (from Latin cattus) + pelose, hairy
ANATOMY
Most caterpillars have tubular, segmented bodies. They have three pairs of true legs on the three thoracic segments, up to four pairs of prolegs on the middle segments of the abdomen, and often a single pair of prolegs on the last abdominal segment. There are ten abdominal segments. The families of lepidoptera differ in the numbers and positioning of the prolegs. Some caterpillars are fuzzy (which means they have hair) and they are most likely to cause itching of the hands if touched

Caterpillars grow through a series of moults; each intermediate stage is called an instar. The last moult takes them into the inactive pupal or chrysalis stage.

Like all insects, caterpillars breathe through a series of small openings along the sides of their thorax and abdomen called spiracles. These branch into the body cavity into a network of tracheae. A few caterpillars of the family Pyralidae are aquatic and have gills that let them breathe underwater.[2]

Caterpillars have 4,000 muscles (compare humans, with 629). They move through contraction of the muscles in the rear segments pushing the blood forward into the front segments elongating the torso. The average caterpillar has 248 muscles in the head segment alone.

SENSES
Caterpillars do not have good vision. They have a series of six tiny eyelets or 'stemmata' on each side of the lower portion of their head. These can probably form well focused, but poorly resolved images.[3] They move their heads from side to side probably as a means of judging distance of objects, particularly plants. They rely on their short antennae to help them locate food.

Some caterpillars are able to detect vibrations, usually at a specific frequency. Caterpillars of the common hook-tip moth, Drepana arcuata (Drepanoidea) produce sounds to defend their silk nests from members of their own species,[4] by scraping against the leaf in a ritualized acoustic duel. They detect the vibrations conducted by the plant and not air-borne sounds. Similarly, cherry leaf rollers Caloptilia serotinella defend their rolls.[5] Tent caterpillars can also detect vibrations at the frequency of wing beats of one of their natural enemies.

Hi Durzan,
A very colorful caterpillar captured with great sharpness.
Lovely patterns and colors on the body.
I wonder what it will grow into when it grows up. : )
Great DOF.
TFS. : )

Hi Durzan,
A perfect sharpness! ... excellent colors, very well made and blur in the background. Good lighting. This is a truly beautiful insect. I had never seen before. Thanks for sharing, very good job.

Regards, Jesús

Ciao Durzan, lovely caterpillar with fantastic colors, beautiful macro with wonderful blurry BG, fine details and excellent sharpness, very well done, ciao Silvio

Selam Durzan, nefis bir atmaca güvesi tırtılı. Türünü bilmem ama, tırtılın gerisindeki çıkıntılı yapı atmaca güvelerinde (hawkmoth) var. Detaylar, kompozisyon, SDZ ve art aslanın pürüzsüzlüğü ile süper bir makro olmuş. Senin 105 mm de neredeyse bendeki Micro-Nikkor kalitesinde. Bu da mercekten çok deklansöre basanın çok daha etkin olduğuna da bir emsal.
Eline ve emeğine sağlık.
Selamlarımla.
Bayram

Durzan merhaba,nefis bir tırtıl fotoğrafı.Netlik ve kontrast çok güzel,artalan süper.Bu tıytıyı çok sevdim :)Ellerine sağlık,selamlar :)

Hi Durzan.
Brilliant image of the beautiful insect. You have reproduced its colouration, texture, shapes and all other charming details fantastically. Sharpness is spot on. I also impressed with nicely coloured and smoothed BG. It supplements the main character excellently. Bravo. Well done.
