Coleoptera Most live in substrate: Respiration Respiration Respiration

Hutchins, Eddie, Morning On-Air Personality has reference to this Academic Journal, PHwiki organized this Journal Coleoptera ~ 5,000 aquatic beetles worldwide Most live in substrate: Adults usually leave water temporarily – dispersal. One time – Elmidae (riffle beetles) Several times – Dytiscidae, Hydrophilidae Respiration 1. Self-contained air reserves (Dytiscidae – diving beetle) 2. Transcuticular respiration (gills in larvae) 3. Plastron respiration (adult Dryopidae) 4. Piercing plant tissues (larval Chrysomelidae) Slender antennae Hind coxae extend posteriorly divide first abdominal segment Swimming hairs on legs

Varied life histories Some larvae occur year round, adults as long as short period (Psephenidae) Water pennies Larvae are aquatic, adults terrestrial Varied life histories Others occur as larvae in addition to adults year round – Elmidae = riffle beetles Long antennae 5-segmented tarsi Crawl on bottom – do not swim = no swimming hairs on hind legs 5-6 abdominal segments Varied life histories Others have long adult; larva only around a few weeks – Hydrophilidae Water scavenger beetles Adult 3 segmented club antennae 5 segmented tarsi Larvae Large m in addition to ibles 4 segmented legs

Scirtidae = marsh beetles Small (5 – 15 mm) Larvae have long antennae 4-segmented legs, single claw Beetle pupae are mostly terrestrial Under stones or logs Few marine beetles – substrate dwellers Larval morphology = diverse Sclerotized head capsule M in addition to ibles, maxillae, labium Gill-like appendages in some (Gyrinidae = whirligig beetles)

Coleoptera The key 2 compound eyes that appear to be divided = Gyrinidae, whirligig beetles Eyes not divided, hind coxae divided into plates that cover abdominal segments 1-2, or 3 Haliplidae, crawling water beetles

Hind coxae not exp in addition to ed into plates, divide abdominal segment 1 Dytiscidae, predaceous diving beetles Hind coxae not dividing abdominal segment 1, antennae clubbed with cuplike segment at base Hydrophilidae, water scavenger beetles Antennae short with comb-like club, body length 5-6.5 mm Dryopidae, long-toed water beetles

Antennae w/o comblike club, body length < 4.5 mm Elmidae, riffle beetles Hutchins, Eddie KMGN-FM Morning On-Air Personality www.phwiki.com
