### Identification The Dusky Spitting Spider (*Scytodes fusca*) is a master of understated camouflage. Look for its most distinctive field mark: a high-domed, "hunchback" cephalothorax that is notably larger and more bulbous than its abdomen. This oversized head houses specialized silk-glue glands. Measuring roughly 4–6mm, its body is a velvety, muted brown or charcoal, often decorated with subtle, dark mottling. Unlike many common spiders with eight eyes, *S. fusca* possesses only six, arranged in three distinct pairs. Its legs are long, spindly, and lack the bold banding seen in its cousin, *S. thoracica*.
### Habitat & Range A true cosmopolitan traveler, this species is pantropical, thriving in warm, humid environments worldwide. While it naturally dwells under peeling tree bark or within rocky crevices, it has become a "synanthrope"—a species that lives alongside humans. You are most likely to encounter one in the quiet, dark recesses of a home: tucked behind a bookshelf, inside a closet, or shadowed behind a picture frame.
### Behaviour Observed in the field, *S. fusca* appears slow, almost mechanical. It is a strictly nocturnal prowler that does not spin a traditional web to catch food. Instead, it stalks prey with extreme caution. When a female carries eggs, she does so in her chelicerae (mouthparts), protected by a thin silk veil, showcasing a rare level of maternal investment for such a small arachnid.
### Diet This species is an insectivore, specializing in "spitting" to hunt. It targets small flies, moths, and silverfish. Once within range (about 10mm), it oscillates its fangs to spray a twin stream of sticky, venom-infused silk in a precise zigzag pattern, instantly pinning the victim to the substrate before delivering a final, paralyzing bite.
### Fascinating Fact The "spit" of *S. fusca* is one of the fastest biological actions on Earth. The silk-glue mixture is ejected at a staggering 30 meters per second; the entire attack—from the moment the spit leaves the fangs to the immobilization of the prey—takes less than 1/700th of a second!
