In some insects the legs are adapted for walki ng, running, jumping, grasping, digging, or swimming. In this lab you will examine a number of different insects with legs modified for various functions. You will also prepare drawings for some of them. For each drawing you should label all of the typical leg structures: coxa , trochanter , femur ...
Each leg has six major components, listed here from proximal to distal: coxa (p1. coxae), trochanter , femur (p1. femora), tibia (p1.tibiae), tarsus (p1. tarsi), pretarsus . The femur and tibia may be modified with spines.
Insect legs are typically 6-segmented (coxa, trochanter, femur, tibia, tarsus, pretarsus) usually having only one trochanter and lacking a patella. The tarsus is subdivided and there is typically a 2-
Basic Insect Morphology. The following diagrams outline common characteristics found in insect anatomy, including detailed parts of wings, legs, and head. Three parts of an insect: head, thorax, abdomen. Humans have a head, torso (similar to thorax) and abdomen.
Insect legs have numerous adaptations that depend on the insect’s lifestyle. Here are two examples. At top, a leg from an aquatic insect (note the numerous fine hairs that spread for swimming) it is also used to name the basic leg parts. At bottom, raptorial forelegs from a mantispid (mantidfly) used for seizing prey then clamping during ...
The three pairs of jointed legs originate from the thorax. Insect legs differ based on their mode of movement and are often useful in identifying insects. Some examples of different types of legs based on the insect’s movement include walking, jumping, and swimming. Some legs are adapted for specific uses such as carrying pollen or capturing ...
Easy to read text of key diagnostic characters accompanies 670 color images of insects, related groups, and important anatomical features. Specimens have been photographed alive and/or on pins, and in most images a neutral background of gray has been inserted to allow subjects to stand out.
