lntroduction
The guild concept has been widely applied in both aquatic
and terrestrial environments to describe the spatial and
temporal strilcture of ecological communities, usually wi&
respect to the different ways in which animals H (Root

et a1.2ffi. Maay studies of guild structure involve analyses
of temporal changes in single assemblages (e.g Posey er aL
1998), while others investigate differcnces betweea geographically
isolated but fundamentally similar habitats, such as
aquatic habitats on different coastlines (e.g. Verrneij, Dietl &

Reid 2008). Few studies in comparisoa have investigated
differeaces in guild structure bstneen different microhabitats
at single sites (e.g. Joern & Lawlor 1981; Stork & Blackburn
1993).
High species richness, in particular among arthropod communities
within forest canopies, is facilitated by the concentratioo
of large quantities of diverse resources (Lowman &
Moffett 1993). Although the positive relationship between
resource diversity and biodiversity is a simple predictioo,
assessments of the feeding guild structure of insect assemblages
inhatiting different microhabitats are lacking and
have either been carried out on the mature leaf assemblage
only (Basset l99zbr, or at the scale of tle whole tree,
with little consideration for host tree phenology (Moran &
Southwood 1982; Stork 1987; Basset l99lb; Kruger &
McGavin 2fi)l). However, it is a reasoaable as$umption that
