Galls on Ashe Juniper (Juniperus ashei)
by Bob Harms
The terminal yellowish
scales enveloping a reddish-brown-tipped structure (pictured below) of
January branchlets of J. ashei were studied in the hope that they
represented ovulate cones. Instead, the brown-tipped structured was
discovered to be a loose fusion of two scales containing a bright orange
larva - i.e., it was a gall Walshomyia texana (with thanks to Harlin Hanson for tracking this down). The larva is that of a gall midge (noted in R.H. Painter, The biology of some dipterous gall-makers, Journal of the Kansas Entomological Society 8, 1935).
The images were scanned directly from branchlets collected in
mid January, 2000.
