Specimen labels. This species is, in a simple sense, the most common and widely distributed Dolichoderus species in southeast Asia. Yet the form subsumed under this name appear to include a number of species that show consistent ecological and life history differences but are hard to distinguish morphologically see the nomenclature section below.
Palaearctic Region : China. Check data from AntWeb. Emery [Java: in Dischidia rafflesiana Wallich, parabiosis with Crematogaster sp. Lycaenidae ]; Jacobson [Java: variable nesting behaviour, often between joint leaves; trophobiosis with aphids, coccids, membracids; prey Ptilocerus ochraceus Montandon Reduviidae ]; Emery 13, pl.
Planococcus lilacinus Cockerell Pseudococcus crotonis auctt. Steatococcus Ferr. The following papers deal with the usage of D. Pseudococcidae: Cataenococcus hispidus Morrison , Maconellicoccus hirsutus Green , Planococcus lilacinus Cockerell , Pseudococcus elisae Borchsenius, now known to be P. Dolichoderus thoracicus , together with Anoplolepis gracilipes and Oecophylla smaragdina , is one of the most common ant species which tends honeydew-producing hemipterans in Indonesia.
Fanani et al. They found that when ants were absent the average time spent foraging by individual parasitoids was significantly longer As a result, parasitoids spent less time in finding hosts and a longer time in handling hosts.
This resulted in more oviposition activities and a fold increase in parasitism and the number of wasps that emerged from their hosts. The fruiting body of the fungus forms a cavity structure containing debris. They found these cavities function as nest sites for the ants. Even in mature fungal samples, which are naturally degraded with exposed carton-like structure, ants were still observed nearby.
The ants utilize the fungal fruiting body as nests, the hard and tough structure of the fungus protecting the ants from an otherwise harsh environment. See on Sketchfab. See list of 3D images. The following information is derived from Barry Bolton's New General Catalogue , a catalogue of the world's ants.
Dill - D. As already stated by Donisthorpe , D. Despite this early synonymization, this species had usually been identified and described as D. While a clear delimination of these forms based upon morphological characters is very difficult, there are in some cases very obvious biological or ethological differences.
For example, the rather rare Dolichoderus sp. For instance, some have rather loose nests with or without fragile carton, while the nests of others are very stabile, multi-chambered out of firm carton material. Again, certain groups build stable-nest pavilions on leaves out of carton or silk see review of literature on biology above.
While, on the one hand, the thoracicus complex seems to consist of various, still unidentified sibling species, there are, on the other hand, several existing taxa that most probably should be lumped. The majority of the many described subspecies is based only on very variable characters, stich as colour or very slight differences in the sculpturing or shape of the propodeum, which may not stand the test of a critical review. Furthermore, a synonymy with thoracicus has been already assumed for Dolichoderus gibbus by Emery , and for Dolichoderus lactarius by Donisthorpe A thorough taxonomic review of this complex appears to be urgently indicated, not at least because of the frequent occurrence, wide distribution and considerable economic importance e.
