Identification & Distribution

Adult apterae of Periphyllus venetianus (see first picture below, with immatures) are shiny, marbled black and green, with pale legs (cf. Periphyllus hirticornis, which is light green). The dorsum is pale membranous, apart from a narrow dark sclerotic band on abdominal tergite VIII, and siphunculi and cauda are dusky (the dark markings on other tergites are not sclerotized, so do not show on clarified mounts). The antennae are pale, except for segments I & II, apices of segments III-V, and all of VI, which are dusky to dark. Antennae are 0.75-0.9 times body length, with the terminal process 3.9-6.9 times the base of segment VI (cf. Periphyllus aceris and Periphyllus testudinaceus, which have the terminal process only 2.0-3.6 times the base of that segment). The rostrum is rather long, reaching to or past the hind pair of coxae, with the apical rostral segment rather short, about equal to the second hind tarsal segment. Dorsal hairs are pale, thin and fine-pointed (cf. Periphyllus hirticornis, which has those hairs blunt or forked). Some hairs are very long, about 7-8 times the basal diameter of antennal segment III, others only one third that length. The siphunculi are truncated conical, about as long as or only a little longer than their basal widths (cf. Periphyllus hirticornis, which has siphunculi at least 1.5 times longer than their basal width). Body length of adult Periphyllus venetianus apterae is 1.1-2.0 mm.

The alate Periphyllus venetianus (see second picture above) has not previously been described. From the photograph shown, the head and thorax are dark, the abdomen is marbled green & black, similar to that of the aptera, but siphunculi are dark, as are the antennae, apart from the base of segment III. Immatures (see first picture above, and two pictures below) are variable in colour, sometimes green, or marbled brown-green or black-green.

Periphyllus venetianus is monoecious on field maple (Acer campestre). They feed on the leaf undersides and petioles. Aestivating nymphs have foliate (=leaflike) marginal hairs. Periphyllus venetianus are sometimes attended by ants. The lifecycle is holocyclic, with immature oviparae having been recorded in Sicily in September. The species is found in southern Europe (Austria, Czechoslovakia, France, Italy, former Yugoslavia). The above images were from Serbia, formerly part of Yugoslavia.


Other aphids on the same host

Periphyllus venetianus has only been recorded on 1 Acer species (Acer campestre).

Blackman & Eastop list 22 species of aphid as feeding on field maple (Acer campestre) worldwide, and provide formal identification keys (Show World list). Of those aphid species, Baker (2015) lists 17 as occurring in Britain (Show British list).


We are grateful to Marko Šćiban for permitting us to reproduce his images of Periphyllus venetianus.

We have used the species account given by Hille Ris Lambers (1960) together with information from Roger Blackman & Victor Eastop in Aphids on Worlds Plants. We fully acknowledge these authors and those listed in the reference sections as the source for the (summarized) taxonomic information we have presented. Any errors in information are ours alone, and we would be very grateful for any corrections. For assistance on the terms used for aphid morphology we suggest the figure provided by Blackman & Eastop (2006).
