I studied the distribution of frass produced by larval Lepidoptera in a latesuccessional,
10-ha forest plot at the Ravenna Army Ammunition Plant in Portage
County, Ohio. From July through September, 1998, fallen frass pellets were collected
from the dominant tree species, American beech (Fagus grandifolia) and sugar maple
(Acer saccharum), using 1m2 frass nets. Two frass nets were placed beneath each
selected tree in three areas of the plot: along a road edge, in the interior ofa forest,
and along the South Fork ofEagle Creek. Frass pellets were collected on a weekly
basis from a total of 120 nets and were weighed to the nearest O.Olg. Frass weights
for beech and maple did not differ between the three transects. However, frass
weights were significantly greater from beech than from maple trees (Mann-Whitney
test, P= 0.01). Frass pellets from the peak collection were also separated into size
classes. Based on weights, the size of frass did not significantly differ between beech
and maple. Live specimens were collected from June through July, 1999 and their
frass pellets were used to develop a key for the identification of 14 late-season
lepidopteran species found in a beech-maple canopy. Two species of geometrid
larvae, Plagodis fervidaria and H}pagyrtis unipunctata, were distributed differently
depending on their host. When feeding on beech, both species were more abundant
on trees located along the creek edge but when feeding on maple, they were more
abundant on trees growing along the road edge (Kruskall-Wallis, P = 0.001). |
