Study Notes
Lepidoptera
- Four membranous wings; hindwings smaller than forewings.
- Mainly covered with scales; mouthparts adapted for sucking.
- Some adults lack mouthparts and do not feed.
Coleoptera
- Largest insect order, with around 300,000 to over a million species.
- Highly variable size, with the heaviest insects being beetles.
- Four pairs of wings, forewings thickened as elytra covering membranous hindwings.
- Includes diverse habits, with predators like ladybird beetles.
Dermaptera
- Name translates to "skin wing."
- Exhibits gradual metamorphosis.
- Characterized by two pairs of wings, with the front one often reduced and leathery.
- Chewing mouthparts; mostly omnivorous with forceps-like cerci.
- Some species are considered nuisance pests.
Hemiptera
- Known as true bugs; presence of thick front wings and membranous hind wings.
- Triangular structures on the back; pentamerous antennae.
- Features piercing or sucking mouthparts and incomplete metamorphosis.
- Examples include bed bugs and chinch bugs.
Orthoptera
- Name means "straight wing."
- Shows gradual metamorphosis with leathery forewings.
- Possesses chewing mouthparts; hind legs adapted for jumping.
- Mainly phytophagous and capable of sound production using the tympanal organ.
Mantodea
- Name translates to "soothsayer" or "prophet."
- Possesses gradual metamorphosis; forewings are leathery.
- Equipped with chewing mouthparts and predatory raptorial front legs.
- Reproduces by laying eggs in ootheca.
Blattodea
- Derived from the Greek word "blatta" meaning cockroach.
- Features gradual metamorphosis and usually leathery wings.
- Chewing mouthparts and primarily omnivorous; cursorial legs for speed.
- Some species exhibit social behavior; eggs laid in ootheca.
Phasmatodea
- Name means "apparition" or "phantom."
- Exhibits gradual metamorphosis with reduced or absent wings.
- Foliage feeders with a cryptic appearance, often nocturnal.
- Sexually dimorphic species that can reproduce parthenogenetically; regenerative capabilities.
Odonata
- Name means "tooth," indicating predatory nature.
- Undergoes incomplete metamorphosis; aquatic naiads.
- Two pairs of elongated wings with complex venation; chewing mouthparts.
- Both naiads and adults are predatory; males of the species are territorial.
Siphonaptera
- Characterized by a short lifespan and not highly diverse.
- Considered primitive, appearing early in the fossil record.
- Lifecycle includes larva, pupa, and adult stages; known to spread diseases.
Mallophaga
- Encompasses around 2,600 species of chewing lice.
- Features a triangular head broader than the thorax and a flattened body.
- Simple metamorphosis; ectoparasitic, feeding on skin or feathers.
- Transmitted through contact with other animals.
Anoplura
- Includes around 2,400 species of wingless ectoparasites with sucking mouthparts.
- Smaller size, flattened body, reduced eyes, and clawlike tarsi for gripping.
- Exhibits incomplete metamorphosis, with strong host specificity (mammals only).
Collembola
- Named for the collophore; small, primitive hexapods.
- No metamorphosis; adults continue to molt.
- Primitively wingless with chewing mouthparts.
- Capable of jumping using furcula and tenaculum; primarily feed on fungi, common in soil and leaf litter.
Diplura
- Includes approximately 800 species; less species-rich than Collembola.
- Substantial diversity in habitat preferences and lifestyles.
