Neuroptera Larvae
|
Very similar in appearance to Coleoptera larvae. All are predators.
Generally: - distinct head w/ well defined, forward directed mandibles, and usually a distinct antennae - distinct thorax & well segmented legs - abdomen w/ 9-10 segments |
|
Coleoptera Larvae
|
Great diversity of forms and habits. May be predator, herbivore or scavenger.
Generally: - well defined head w/ mandibles - three thoracic segments with one pair of spiracles, and three pairs of segmented legs (generally elbowed w/ claw or claws, a few fams are legless) - abdomen w/ 8-10 segments and pairs of spiracles on segments 1-8 |
|
Lepidoptera Larvae
|
Less diversity of form than Coleoptera. Most are herbivorous.
Generally: - distinct head w/ ventrally directed mandibles - three distinct thoracic segments bearing one pair of spiracles, and 3 pairs of segmented legs(legs are generally curved, not elbowed) - 10 abdominal segments w/ pairs of spiracles on segments 1-8 -abdomen w/ 2-5 pairs of fleshy prolegs always bearing crochets (prolegs found on segments 3-6 and 10) |
|
Diptera Larvae
|
found in great diversity of habitats, nearly 50% of species are aquatic
Generally: - may or may not have distinct heads - mouthparts may be crude hood, or mandibles when head is present - 11 body segments, w/o distinct thoracic or abdominal region - Legs usually absent - Variable spiracles |
|
Siphonaptera Larvae
|
Occur in host's nesting materials or in substrate near host's resting site.
Generally: -long and cylindrical w/ elongated head bearing forward directed mandibles - Indistinct thorax and abdomen, clothed w/ long setae on all segments - Legs are absent except for short pointed fleshy prolegs on last abdominal segment. |
|
Hymenoptera Larvae
|
- Most larvae are from parasitic or social species and are unlikely to be observed. Some are pests (mostly sawflies)
Generally: - distinct head w/ mandibles usually directed ventrally; three distinct thoracic segments w/ one or two pairs of spiracles and three pairs of segmented legs; an abdomen with 10 segments - abdomen usually has 6-8 pairs of fleshy prolegs without crochets |
