Arthropods are classified based on the number and structure of their?
Legs. 6: Insect 8: Arachnid 10 or 12: Crustacean More than 12: Centipede or Millipede.
What is the last of the three segments of an insect?
abdomen
What is an antennomere?
An antennomere is any of the segments of an insect's antenna, in cases where all segments are more-or-less uniform, such as in millipedes.
How many segments are there in a honeybees body?
Three (3) is the number of segments in a honeybee's body. Typical of an insect, the honeybee (Apis spp) showcases a body divided, from front to back, into head, thorax, and abdomen. Honeybees also have segmented antennae and legs.
What is the middle part of an insect's body where the legs are attached?
The head is the first part, with antennae, eyes and mouthparts. The thorax is the middle, with the legs and wings if the insect has them, and containing the muscles to use them. The third part is called the abdomen, with no appendages. This part houses the internal organs.

How many body segments and legs do insects have?
Insects typically have six or eight legs. Their legs are usually attached to the thorax, or center portion, of the insect's body.

What is attached to an insect's thorax?
Attached to an insect's thorax are * The head * The abdomen * Six legs * Two or four wings (occasionally absent)There are several things attached to the insect's thorax. The thorax is attached to the head, legs, wings and abdomen.
How has the appendages of arthropods changed over evolution?
The modifications of arthropod appendages has shaped the formation of different groups, such as centi/millipedes, crustaceans, arachnids and insects. The most primitive arthropods are centipedes and millipedes, using all their legs as walking legs. More advanced groups, differing from this ancestral state, modified their walking legs into mouthparts, antennae, pedipalps (arachnids) or flippers (crustaceans, look at a lobster tail). Look carefully at an insect face and you'll see it's a fused mess of segments with the legs still attached! Stick insects and beetles are a good example, other groups have modified their palps (mouth-legs) into unrecognizable structures such as mosquito or butterfly probosci.
What are the three segments of an insects body?
All insects, though not always easily visible, have three body segments. First there is the head, then the Thorax, which is also known as the waist of the insect. Lastly there is the abdomen or backside of the insect.
What are the three main body segments of insect?
Head, thorax and abdomen.

What is Insect morphology?
Insect morphology is the study of the form and structure of insects, encompassing their external and internal features. It examines various anatomical aspects, including body segments, appendages, and specialized structures such as wings and mouthparts. Understanding insect morphology is crucial for taxonomy, ecology, and evolutionary biology, as it provides insights into how insects adapt to their environments and interact with other organisms. This field also aids in identifying species and understanding their life cycles and behaviors.
Does an insect primarily have muscle attached to the exoskeleton?
An insect has primarily muscle attached to the exoskeleton. The muscles are made from some substance which is known as chitin.
Reasons why butterflies are arthropods?
They are (by definition) considered insects. They are in the insect order Lepidoptera and are classified with insects because they have a head, thorax, and abdomen. They also have three pairs of walking legs, antennae and a pair of wings-which are the characteristics of most insects.
