Cockroach nymph (often German cockroach Blattella germanica or American cockroach Periplaneta americana)
Not a spider (Blattodea order, likely a cockroach nymph)
Blattidae or Ectobiidae, Order Blattodea (Cockroaches)
Physical Description
Oval, flattened body with distinct head, thorax, and abdomen segments. Unlike spiders which have two body segments and eight legs, this organism has three body segments, six legs, and two long, prominent antennae.
Size Estimate
Small nymph, approximately 5 to 10 millimeters in length including antennae.
Coloration & Markings
Reddish-brown to dark brown coloration, often with lighter banding on the thorax depending on the exact species and developmental stage.
Web Type
None. This is an insect and does not spin webs.
Eye Arrangement
Two compound eyes located laterally on the head capsule.
Leg Characteristics
Six walking legs adapted for fast running across flat surfaces, featuring small spines for traction.
Venom & Safety Information
Venom Information
Does not possess venom. It is an insect, not a venomous arachnid.
Medical Significance
Does not bite humans under normal circumstances, but can act as an allergen producer and mechanical vector for bacteria.
Safety Recommendations
Maintain cleanliness, seal food containers, eliminate moisture sources, and consult pest control if an infestation is suspected.
Habitat & Behavior
Habitat & Range
Cosmopolitan distribution; commonly found in human dwellings, kitchens, bathrooms, dark crevices, and warm, humid areas.
Behavior & Temperament
Thigmotactic and nocturnal. Highly agile and fast-moving, scrambling for cover when exposed to light.
Diet & Prey
Omnivorous scavenger feeding on organic debris, food crumbs, paper, and waste.
Seasonal Activity
Active year-round indoors where climate control provides stable, warm conditions.
Description
Although submitted for spider identification, this image clearly depicts an insect nymph belonging to the order Blattodea, commonly known as a cockroach. It features the characteristic six legs and long antennae that distinguish insects from arachnids.
Key Features
Presence of six legs instead of eight, two long multi-segmented antennae, and three distinct body parts.
Similar Species
Various species of cockroaches at different nymphal stages, or occasionally ground-dwelling beetles.
Life Cycle
Incomplete metamorphosis (hemimetabolous), progressing from an egg case (ootheca) through several nymphal instars to an adult.
Ecological Importance
Serves as a food source for numerous predators in natural ecosystems, though domestic species act primarily as household pests.
Conservation Status
Not applicable; common pest species with extremely high and stable populations globally.
Interesting Facts
Cockroach nymphs can regenerate lost limbs during their molting phases and can run at incredible speeds relative to their tiny body size.
Photography Tips
Use macro lighting and a steady hand to capture close-up details of the head, antennae, and thoracic segments for precise pest identification.
