Abstract The evolution of life history characters, in-
cluding parental care behaviors, depends on costs and
benefits. When offspring can influence parental behav-
iors, parent-offspring conflict over parental care can oc-
cur, but only if these parental behaviors are costly.
Mother burrower bugs (Sehirus cinctus) exhibit extended
and complex care of offspring. Mothers guard eggs until
hatching and then attend and provision offspring for ap-
proximately 2 weeks after hatching. Using four experi-
mental treatments, we attempted to identify the costs as-
sociated with specific components of these behaviors.
Under laboratory conditions, egg guarding increases inter-
