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
