💡 Everyday Comparisons for Size, Mass & Speed

💡 Its body length of 15 mm is slightly smaller than the diameter of a 10-won coin (18 mm).
💡 It survives only in human dwellings, requiring water, food, and shelter, with cold being its greatest limiting factor (University of Florida UF/IFAS).

#독일바퀴#Blattella germanica

📖 1. Overview

The German cockroach (Blattella germanica) is a small cockroach that lives alongside humans worldwide and can hardly survive without them.

🦴 2. Anatomy & Morphology

Adults are brown to dark brown with two parallel stripes on the pronotum. Males are thin and slender, whereas females are stout with wings covering the entire abdomen.

🔍 3. Ecology & Behavior

It eats almost anything, from table crumbs and pet food to book bindings. The female carries the egg case at the tip of her abdomen until just before the nymphs hatch, and development from egg to adult takes about 100 days.
