Polistes associus is a species of paper wasps belonging to the family Vespidae.
Distribution This species is present in central and southern Europe (Albania, Austria, Bulgaria, Croatia, European Turkey, France, Greece, Italy, Poland, Romania, Ukraine, Yugoslavia), in the Near East, and in the Oriental realm.Fauna Europaea
Description
Polistes associus can reach a body length of about in females, of about in workers.Erol Yildirim, Hikmet Ozbek Polistinae (Hymenoptera, Vespidae) of Turkey
These wasps are characterized by very light eyes, the ocelli arranged according to an equilateral triangle, with completely black mandibles and yellow lateral parts (genae) of the head. The dorsal surface of antennae is black in both sexes, with wide and deep longitudinal groove. Clypeus is uniformly yellow, markedly depressed, with a distinct longitudinal ridge and a black stripe.
The sixth sternit is black. The ventral part of the last abdominal segment is reddish-brown with an apical lighter spot.Libor Dvoraki & Stuart P. M. Roberts>Key to the paper and social wasps of Central Europe (Hymenoptera: Vespidae)
The males are easily distinguishable by the combination of narrow temples and a markedly depressed clypeus. The dorsal length of the apical antennal segment is longer than in similar species.Christian Schmid-Egger, Kees van Achterberg, Rainer Neumeyer, Jérôme Morinière, Stefan Schmidt Revision of the West Palaearctic Polistes Latreille, with the descriptions of two species – an integrative approach using morphology and DNA barcodes (Hymenoptera, Vespidae)
This species is very similar to Polistes nimpha. For this reason the recognition of P. associus females may be problematic.
Biology These wasps parasitize other Polistes wasps of multiple species, especially Polistes atrimandibularis.Biolib and they are parasitized by Strepsiptera species.Jan Smit, John T.
