Several studies have recently focused on the structural pattern of plant–insect interaction
networks. However, insects and plants have dynamic cycles and differ in their level of …

Abstract Treehoppers (Hemiptera: Membracidae) are sap-feeding insects distributed mainly
in tropical regions. Alchisme grossa is a treehopper that has been reported in the Bolivian …

The pronotum is the most distinctive and representative structure in treehoppers. Although
several functions have been proposed for this structure, its involvement in fitness has not …

Alchisme grossa is a treehopper species showing maternal care until at least the third
nymphal instar. A secondary female treehopper has frequently been observed near a family …

1. Treehoppers (H emiptera: M embracidae) exhibit a wide range of social behaviours
related to maternal care and nymphal aggregation. Maternal care represents an investment …

The mechanisms which promote divergence in populations of phytophagous insects using
alternative hosts depend on the characterization of hosts as different selective scenarios and …

Larvae of Leptus hringuri parasitizing families (adult female+ offspring) of the treehopper
Alchisme grossa on two host-plants, Brugmansia suaveolens (BS) and Solanum ursinum …

1. Insects exhibiting parental care usually can discriminate between kin and non‐kin
individuals, allowing parents to avoid investment in foreign offspring. 2. This study …

Seventy years after Dobzansky suggested that biotic interactions are more important in the
tropics, ecologists are still assembling evidence and elucidating potential mechanisms …

Treehoppers (Membracidae, Hemiptera) may be best known for their sometimes bizarre
morphology and colouration, but they also exhibit interesting and varied maternal care. Eggs …
