Some members of Rhynchitinae develop in
buds, and can be pests by damaging blossom, an
example being the North American “rose curculio”
Merhynchites bicolor, which attacks the buds of
cultivated roses. Others, such as Rhynchites bacchus
and R. auratus develop inside stone fruits such as
apricots, cherries, and sloe berries, and are
regarded as minor pests.
nitens (Attelabinae). The “thief weevils” of
North America (Attelabinae: Pterocolini)
show similar behavior
The female then cuts off the supply of nutrients to
the leaf, so it begins to wither and die, and the larva
is able to feed on the dying leaf, while protected
from predators, parasites, and desiccation inside the
leaf roll. Some attelabines roll numerous leaves on
the same tree, making it look like the tree is covered
with small fruits. The leaf rolls are distinct, and
it is often possible to recognize which species of
attelabid has constructed them.
left | Apoderus
This is a species
from Malaysia,
but similar-looking
Apoderini occur
worldwide. Most
of them make tight,
cigar-shaped rolls from
the leaves of a single
species of tree.
below | Byctiscus betulae
This beautiful European
species is not very
host-specific and
rolls the leaves of
multiple species
of trees and shrubs.
It can be a pest
of grapevines.
opposite | Trachelophorus giraffa
This large, red and black species shows
marked allometric growth of the head
and thorax, and the elongated neck
(hence the name Giraffe Weevil) is used
in competitions between males.
