Harvestman The Biology Of Opiliones Cluster

I’m about half-way through the “” – this is a -project devoted to sharing facts about Harvestmen (follow using the hashtag #OpilionesProject). As I was working through some of the chapters, I gave a lot of attention to the variety of common names given to Harvestmen, including Daddy Longlegs. This is not a very good common name for Opiliones because the characteristic of ‘long legs’ is not common to all Harvestmen, and many species (especially in tropical regions) are rather stout and don’t have the long, dangly, legs that we often associate with Opiliones in more northern regions.The other reason to avoid the name daddy longlegs for Harvestmen is because of the confusion it creates with respect to a distant relative of Harvestmen – a spider with the latin name of Pholcus phalangioides.

Harvestman The Biology Of Opiliones Clusters

This species is often referred to as the “ Daddy longlegs spider” (and, by the way, the name “Phalangida” has historically been used as a synonym to Opiliones – more confusion!). The rather obvious similarity between northern Harvestmen and Pholcus phalangioides is that they both have long legs – but it stops there. Spiders have a narrow waist (i.e., the constriction between the cephalothorax and abdomen) whereas Harvestmen do not. Pholcus phalangioides is also an enthusiastic web-builder whereas Harvestmen do not live in webs. Here’s a photo of Pholcus phalangioides, courtesy of. (thanks, Ashley, for permission to use your photograph!). A cellar spider, with prey (c) A.

BradfordComparing a Spider to a Harvestmen is like comparing a blue whale to a chimpanzee. Spiders are a different order (Araneae) than Harvestmen (Opiliones), and although both Arachnids, they diverged millions of years ago. Opiliones are more closely related to, and than they are to the Araneae.The other common name for Pholcus phalangioides is the “ cellar spider” and this is much more appropriate – these spiders are synanthropic (see my other posts about spiders that like living in or near your home, the & the ), and are very commonly found in dark, damp places in and around human structures. In my own house, the garage and basement are the common habitats. Pholcus phalangioides is very distinctive – in addition to its long legs, it is a fascinating species from a behavioural perspective – if disturbed, it gyrates and whirls around in an impressive display of arachno-energy. This is something I encourage you to try with your own populations of the species – it is wonderful to watch.

Date Published:Jan 7 Abstract:Opiliones are one of the largest arachnid orders, with more than 6,500 species in 50 families. Many of these families have been erected or reorganized in the last few years since the publication of The Biology of Opiliones. Recent years have also seen an explosion in phylogenetic work on Opiliones, as well as in studies using Opiliones as test cases to address biogeographic and evolutionary questions more broadly.

Accelerated activity in the study of Opiliones evolution has been facilitated by the discovery of several key fossils, including the oldest known Opiliones fossil, which represents a new, extinct suborder. Study of the group's biology has also benefited from rapid accrual of genomic resources, particularly with respect to transcriptomes and functional genetic tools. The rapid emergence and utility of Phalangium opilio as a model for evolutionary developmental biology of arthropods serve as demonstrative evidence of a new area of study in Opiliones biology, made possible through transcriptomic data.
