	abstract = {<p>The Drosophila cuticle carries a rich array of morphological details. Thus, cuticle examination has had a central role in the history of genetics. Studies of the Drosophila cuticle have focused mainly on first-instar larvae and adult cuticular morphology. Although the cuticles of second- and third-instar larvae are strikingly different from those of the first instar, these differences have been poorly studied. This protocol describes three methods for preparing cuticles from fed larvae. One commonly used procedure involves manually pricking the larvae. A simpler method for preparing larval cuticles is to burst the larvae once they have been mounted. This method is used for first- and second-instar larvae and does not require pricking; it removes the gut contents by "popping" the rear of the embryo using pressure from the coverslip. If just the right amount of medium is used, the coverslip will be pulled toward the slide, applying pressure on the samples. The larvae usually burst from their posterior ends. Also presented is an alternative procedure designed specifically for the use with third-instar larvae, although the "pricking" method can be used at this stage.</p>
