Black Hole Spider for sale from Big Z's (Kukulcania hibernalis). Spice-rated keeper notes, care guidance, and live-arrival packing where eligible.
Kukulcania hibernalis (Black Hole Spider / Southern House Spider)
The easiest, most hands-off display spider in the hobby, and one of the cheapest ways to put a real web-builder on your shelf. This jet-black crevice weaver moves into a crack, spins a flat mat of woolly lace around the entrance, and turns one corner of the tank into a living trap you get to watch work every night. Big for a house spider at a 2 to 3 inch leg span, harmless to people, and she can hold the same doorway for years. Grab a Black Hole Spider today and give your collection the web everyone asks about.
Why do hobbyists keep Kukulcania hibernalis?
-
The Web: a wide mat of cribellate lace that funnels into one dark hole. It grows every week and it works: anything that touches it gets pulled in.
-
Hands-Off and Harmless: shy, reluctant to bite, and not medically significant. The perfect first true spider and a safe one for a kid's room.
-
Years of Display: females are long-lived and almost never leave the retreat. Set it up once and watch it for years.
-
Tiny Footprint: a small enclosure is all she needs. A big show in a small cube.
How should Kukulcania hibernalis be kept?
-
Adult Size: females reach a 2 to 3 inch leg span with a thick, velvet-black body. Males are smaller, brown and long-legged (and get mistaken for brown recluses every spring).
-
Enclosure: a 4 to 8 inch cube is plenty. Lean a slab of cork bark against the glass or give her a slot in a piece of wood: the crevice is the whole setup. She builds the web around its mouth.
-
Temperature: 70 to 85 degrees F. Normal room temperature is perfect.
-
Humidity: dry-leaning. Coco fiber or sand kept mostly dry with a light mist on the walls once a week.
-
Water: she drinks the mist. A bottle-cap dish is optional.
-
Diet: crickets or small roaches once or twice a week, dropped near the lace after dark.
-
Temperament: secretive and calm. A display animal: she lives in the crevice, you watch the lace move. Handling is not needed and not recommended.
Are there any additional notes or considerations?
-
Wild-Caught: field-collected adults and subadults from the Southeast, settled and feeding.
-
Patience Pays: she builds the retreat in the first few nights and the web only grows from there. Do not clean the lace away; it is the attraction.
