Panel #1 - Halberd: technically, the pictured weapon is not a halberd because it doesn't have the apical spike or reverse beak. Plus, it has a strange, serrated circular blade at the other end of the pole. Obviously, bipedal arthropod weapon technology has departed from our own. To learn more about halberds in human history, check out this Wikipedia entry.
Panel #2 - The orange bug is correct. Insects do not have skin. Insects have an exoskeleton which is a hard outer covering made mostly of chitin (pronounced kytin). Your homework for the weekend is to write a five page essay comparing and contrasting the pros and cons of skin versus chitin.
Panel #3 - Chic is a French word meaning smart or stylish. (French is a language often used by giant, subterranean, bipedal arthropods.)
Panel #4 - Dung beetles are beetles that feed on feces. Obviously, the orange bug thinks little of this practice or he wouldn't use it as an negative and derogatory vulgarity.
Panel #6 - Glaive: A glaive is a polearm consisting of a single-edged blade on the end of a pole.
Guisarme: A polearm with a hooked blade on the end used to pull horsemen off their mounts.
Panel #7 - Malphigian tubules: A type of excretory and osmoregulatory system found in some insects.
Panel #8 - Vogue: The prevailing fashion, practice, or style.
Panel #9 - Pop Quiz: Which shield will the bug pick?
