An attelabid weevil,Euops splendida, the female of which makes leaf-roll cradles, is symbiotic with a fungus. She possesses a set of fungus-cultivating structures: spore reservoir, spore incubator, and spore bed, and also comb plate which is used for sowing spores in the nibbled sites on the cradle leaf. 
Naphthalenones from a Perenniporia sp. inhabiting the larva of a phytophagous weevil, Euops chinesis.
The new naphthalenone derivatives perenniporides A-D (1-4) were isolated from solid cultures of a fungus Perenniporia sp. inhabiting the larva of Euops chinesis, a phytophagous weevil with high host
Farming of a defensive fungal mutualist by an attelabid weevil
This study investigated how the weevils create cradles (leaf-rolls) for their offspring and protect the fungal garden, and described new specialized structures and behaviors that E. chinensis females use for leaf-rolling and fungus inoculation.
Host specificity of Euops chinesis, a potential biological control agent of Fallopia japonica, an invasive plant in Europe and North America
As larval development appears to depend on a fungus in the leaf rolls, the insect–fungus mutualism and risks including host specificity of the fungus should be evaluated before the insect’s introduction.
Evolutionary History of Maternal Plant-Manipulation and Larval Feeding Behaviours in Attelabidae (Coleoptera; Curculionoidea) and Evolution of Plant-Basal Weevil Interaction
Molecular phylogenetic analyses based on the nuclear 18S and 28S ribosomal DNA and the mitochondrial COI genes indicated that the maternal plant-cutting behaviour originated in a common ancestor of Attelabidae, but was subsequently lost in the several lineages.
A leaf-rolling weevil benefits from general saprophytic fungi in polysaccharide degradation
It is concluded that saprophytic fungi form facultative associations with H. bicallosicollis and benefit weevil nutrition by polysaccharide decomposition and highlights the significance of fungal symbionts in insect nutritional ecology.
Contribution of symbiotic mycangial fungi to larval nutrition of a leaf-rolling weevil
The mutualism between Euops and its mycangial fungi contrasts with the mainly nutritional mutualisms between wood-infesting insects (termites, bark/ambrosia beetles, and wood wasps) and lignin/polysaccharide-decomposing fungi.
New subfamily of ambrosia beetles (Coleoptera: Platypodidae) from mid-Cretaceous Burmese amber
This is the first described Platypodidae from Burmese amber and the oldest documented ambrosia beetle that demonstrates glandular sac mycangia containing yeast-like propagules and hyphal fragments.


Repositories of Symbiotic Fungus in the Ambrosia Beetle Platypus wilsoni Swaine (Coleoptera: Platypodidae)
Stained sections of female adult Platypus wilsoni Swaine showed that the punctures concentrated on the caudal half of the pronotum are fungus pits or mycangia, which are not found in male adults.
Anatomical and Histological Changes in Internal Organs of Adult Trypodendron lineatum, Gnalhotrichus retusus, and G. sulcatus (Coleoptera: Scolytidae)
Changes during adult life in 3 ambrosia beetles, the striped ambrosia beetle, T. lineatum (Olivier); G. sulcatus (LeConte); and G. retusus (LeConte), were found in midgut epithelium, malpighian
Die Blattrolltechnik Von Apoderus Coryli L. Und Attelabus Nitens Scop. (Coleoptera, Attelabinae)
Diese Schnittart wird bei relativ dunnen Blattern angewandt, welche durch Verdunstung schneller ihren Turgor verlieren als dickere, sodass das Blatt durch die andere Blatthalfte mit dem Strauch verbunden bleibt.
