What is unique about Coleoptera?
What is unique about Coleoptera?
Some species do not have hind wings and their elytra are generally fused together. Coleoptera are the only order of insects that have elytra. This adaptation has enabled them to expand into many habitats such as leaf litter, logs and soil, that would otherwise damage the wings of less well protected insect groups.
What do scarabaeidae feed on?
What Do Scarab Beetles Eat? Most scarab beetles feed on a decomposing matter such as dung, fungi, or carrion.
What is a unique characteristic of a beetle?
A distinctive feature of beetles is their front pair of wings, which are thick, hard, and opaque, without the veins characteristic of most other insect wings. These forewings, called elytra (singular, elytron), serve as protective wing covers for a second pair of functional wings underneath.

What are the major characteristics of insects that belong to Coleoptera?
Coleoptera are holometabolus, thus possess distinct egg, larval, pupal, and adult stages. Beyond that it is difficult to make broad generalizations about the aquatic Coleoptera. Most adults and larvae are substrate dwellers, but some are efficient swimmers (e.g., larval and adult Dytiscidae and Hydrophilidae).
What are the characteristics of Odonata?
Odonata, insect order comprising the dragonflies (suborder Anisoptera) and the damselflies (suborder Zygoptera). The adults are easily recognized by their two pairs of narrow, transparent wings, sloping thorax, and long, usually slender body; the abdomen is almost always longer than any of the wings.
What does a scarab represent?
Along with embodying the concept of existence, development, and growth, the scarab was revered for representing the cycle of life and death: “It was seen as a form of protection,” Love explains. The extraordinary bestial was therefore carved or molded into treasured accessories and amulets throughout centuries.
What is the life cycle of a scarab beetle?
The life cycle includes the egg (laid by the female scarab beetle), larvae which feed and grow and are C-shaped, pupae which are similar to the cocoon stage in moths, and adults which mate and begin the cycle again. Scarab larvae feed on roots, decaying plant material, dung (or poop), and carrion (dead animals).
What are four characteristics of a beetle?
Beetles are like all insects, they have a head, thorax, and abdomen, and six legs. Their bodies tend to be very solid and tough. They have chewing mouthparts and often have powerful jaws.
How do dung beetles get nutrients?
Dung itself consists of metabolic waste products and undigested remains of the original food. However, also other food sources like humus, fungi and carrion are used by dung beetles7, thus questioning dung as the only trophic resource for dung beetles which can supplement them with all mandatory nutrients.
Are dung beetles decomposers?
Dung beetles eat animal feces. Decomposers like fungi and bacteria complete the food chain. They turn organic wastes, such as decaying plants, into inorganic materials, such as nutrient-rich soil. Decomposers complete the cycle of life, returning nutrients to the soil or oceans for use by autotrophs.
How do you identify Coleoptera?
Appearance of Adults:
- Chewing mouthparts (sometimes located at the tip of a beak or snout)
- Front wings (elytra) are hard and serve as covers for the hind wings; meet in a line down the middle of the back.
- Hind wings large, membranous, folded beneath the elytra.
- Tarsi 2- to 5-segmented.
