Lecture 12 Flashcards
what is a carrion community
refers to all organisms involved in a decomposing body
What are 4 species making up the carrion community?
- Necrophagous: 1st decomposers
- Predators of Necrophagus species: feed on necrophagus species
- Omnivorous: feed on body and necrophagous species
4: adventive: accidental visitors
2 examples of necrophagous species
diptera, coleoptera
3 examples of predators of necrophagous species
flies, beetles, wasps
3 examples of omnivorous species
wasps, bees, ants
2 examples of adventive species
springtails, spiders
General Succession of species on a body
- Crime scenes Must Stay Secure So Authorites Preserve Data
- Calliphoridae
- Muscidae
- Sarcophagidae
- Staphylinidae
- Silphidae
- Acalyptrate
- Piophilidae
- Dermestidae
Necrophagous Diptera: calliphoridae`
1st visitor of carrion
stages: egg, 3X larval, pupa, adults
attracted to fresh wounds
true or false necrophagous diptera: calliphoridae complete development after host dies
true
Necrophagous Diptera: acalyptrate
late visitors
necrophagous diptera: sarcophagidae
come after calliphoridae
no egg stage
Necrophagous Diptera: Muscidae
attracted to excrements and urine rather than flesh
found on indoor bodies
Coleoptera: Staphylinidae
important predators of fly larvae and eggs
1st beetle to appear
Coleoptera: silphidae
necrophagous and/or predaceous
Coleoptera: Dermestidae
feed on badly decayed skin
