Grassrange, Montana leafy spurge flea
beetle collections
Over the years we have traveled
with the BLM (Bureau Of Land Management) 3 times to collect leafy
spurge flea beetles from a series of "super sites" in the Grassrange
area. We say thank you to Vic Roberts, the BLM Biological Weed
Control Coordinator for Montana for allowing us to collect on these
sites and helping us with his equipment, knowledge and friendly
patience.
During the Summer of 2004 we collected 1.6 million
flea beetles, many of which went with the BLM but, the majority came
back with us to Madison and Jefferson Counties. In the summer of
2005 we brought many of the teachers and high school students who
attend our
Whitehall
Project Summer Class with us and collected 1.5 million. The
teachers plus the BLM took many releases home with them. The rest
(still slightly over half) we brought home and distributed throughout
the counties.
Every person who cares about the effects of noxious
weeds should have a chance to see the miles of dead spurge and to
collect awesome nets full of spurge killing flea beetles. In
places the foliage (including the few remaining well chewed spurge
plants) will be black with flea beetles. It is also nice to see
the grasses and forbs coming back to create a healthy plant community
after the flea beetles have killed the spurge. See the photo
links below.

leafy spurge covered with flea beetles- mostly Aphthona lacertosa, the black
beetles. Notice that most of the spurge is dead (the dead stems
in the background) and the rest is doomed. Grasses and forbs are
coming back at this site.
