“…The surveyors walked slowly around any potential attractive resource patch included in the selected 1‐ha area for 4 h each day. We split the sampling period into 2 h in the morning (about 10–12 h) and 2 h in the afternoon (about 14–16 h) to cover the daily variability of both pollinator (bees and hoverflies, which are more active in the morning than in the afternoon; D'Amen et al ) and flower communities. Sampling took place when we had suitable weather conditions for pollinators (following Westphal et al ).…”

For plant–pollinator interactions to occur, the flowering of plants and the flying period of pollinators (i.e. their phenologies) have to overlap. Yet, few models make use of this principle to predict interactions and fewer still are able to compare interaction networks of different sizes. Here, we tackled both challenges using Bayesian structural equation models (SEM), incorporating the effect of phenological overlap in six plant–hoverfly networks. Insect and plant abundances were strong determinants of the number of visits, while phenology overlap alone was not sufficient, but significantly improved model fit. Phenology overlap was a stronger determinant of plant–pollinator interactions in sites where the average overlap was longer and network compartmentalization was weaker, i.e. at higher latitudes. Our approach highlights the advantages of using Bayesian SEMs to compare interaction networks of different sizes along environmental gradients and articulates the various steps needed to do so.

New Italian records of Lichenophanes varius (Illiger, 1801) (Coleoptera, Bostrichidae)

Lichenophanes varius (Illiger, 1801) is a Turanic-European-Mediterranean species. In most of European countries, this species is protected at different levels and it is classified as "NT" (Near Threatened) in the IUCN European Red List of Saproxylic Beetles. In Italy, it is classified as "EN" (Endangered). Its larvae are saproxylophagous and develop in branches and rotting trunks of many broadleaved tree genera. Nevertheless, this beetle seems to attack only wood which is already invaded by the mycelia of Biscogniauxia spp. (Pyrenomycetes, Xylariaceae). The Italian distribution and ecology of L. varius are updated on the basis of recent records; the species is recorded for the first time from Calabria, where it was reared from Quercus frainetto Ten. which represent a new host-plant record for this beetle. Finally, the authors discuss the possibility that global warming can promote a resurgence of attacks from the above mentioned phytopathogenic fungi in Italian forests and, therefore, this climatic change can also favour the populations of this red-listed beetle.

“…This situation does not apply on prickly pear plantations, cypress hedge and olive orchard characterized by low plant diversity, which negatively affects that of hoverflies. Thus, hoverflies are adept fliers that interact directly with the vegetation for their dietetics requirements (D'Amen et al 2013).…”

Hoverflies (Diptera: Syrphidae) pollinate plants, predate other insects, and feed on vegetal and decay materials, being used as bioindicators of different ecosystem conditions and processes. The main aim of the present paper is to enhance the bioindicator potential of hoverflies in Algeria (North Africa) by studying the hoverfly communities of six sites with different vegetation and conditions, in the semi-arid Northeast of Algeria: unpolluted riverbank, plant nursery, polluted riverbank, olive orchard (Olea europaea), prickly pear plantations (Opuntia ficus-indica), and a cypress hedge (Cupressus sempervirens).With an entomological net, hoverflies were sampled fortnightly from December 2016 to November 2017. In total 37 species were identified, predominating by the subfamily Erisalinae. The unpolluted and polluted riverbanks, and the plant nursery had the highest species richness with 26, 24, and 23 species respectively, whereas, the lowest species numbers were detected in the prickly pear plantations, the cypress hedge and the olive orchard with 16, 14, and 10 species respectively. One species was new to North Africa (Eumerus etnensis) and other three species new to Algeria (Eupeodes nuba, Paragus vandergooti and Eumerus obliquus). The results of the present paper suggest the need for further hoverfly surveys in other unexplored regions and habitats of Algeria.
