The Cellar Spider (Holocnemus caudatus) is a small, delicate arachnid native to the Mediterranean. While often overshadowed by its more famous relative, the Marbled Cellar Spider (H. pluchei), it shares many of the fascinating "vibrating" behaviors typical of the Pholcidae family.
Body & Appearance: It features a yellowish-grey, elongated body with a characteristic dark longitudinal stripe on the underside. Its legs are exceptionally long and spindly, often featuring white and black rings at the joints.
Size: Males typically measure between 5–5.5 mm in body length.
Native Range: This species is primarily found in Spain and Sicily.
