Figure 5. D2-like signaling promotes spicule insertion attempts.

(A) Duration of vulval contact until spicule insertion or 120 sec. Symbols represent individual male performance. Open symbols represent unsuccessful insertions. (B) Duration over the vulval slit during the 1^st spicule insertion attempt. For A&B, line and error bars represent mean and SEM. (C) Spicule movement frequency calculated for 6 sec during spicule thrust against vulval slit. Symbols represent an individual frequency interval. Line and error bars represent mean and SD.
