Cimex lectularius
General info
Phylum: Arthropoda
Class: Insecta
Order: Hemiptera
Size: 5 mm
Food: blood
Habitat: bedrooms
Distribution: cosmopolitan
Relationship with humans: parasite

Bedbugs are unpleasant tenants in human bedrooms. Both adults and nymphs are parasites, living by sucking blood from warm-blooded hosts - mammals and birds. They acquire blood using their proboscis, which has the ability to puncture skin and draw out blood. A hungry individual has a flat abdomen, while a full one is rounded. To sate its appetite, this insect needs 4-7 mg of blood. Bedbugs are active at night; during the day they hide in cracks, usually in higher locations. They leave behind specks of waste with a characteristic odor. Bedbugs can move very quickly and can survive without food for a long time. Females lay 100-200 eggs, but before doing so, they must suck up an adequate amount of blood. Bedbugs are found on all continents except Antarctica.
