Observations on girdling behavior of Phytoecia rufiventris. (a) Behavioral sequence of girdling and oviposition of P. rufiventris. (b) Girdle angles of lower and upper girdling (N = 100). Box indicates 1st and 3rd quantiles. (c) Morphology of naturally girdled E. annuus. Two girdles are indicated with white triangles. (d) Trypan-blue staining of the experimentally girdled and non-girdled stem of E. annuus at 1 and 3 wpg. Blue staining indicates cell death
