Takecallis arundinariae

Black-spotted bamboo aphid

Identification & Distribution  Other aphids on the same host 

Identification & Distribution:

Adult viviparae of Takecallis arundinariae are all winged. Alates are whitish, pale yellow or greyish-yellow. The thorax has variably developed longitudinal dark stripes, and the abdomen has a pair of elongate dark patches on each tergite. The third antennal segment is dusky to dark except, at the very base, and has the most proximal secondary rhinarium situated close to its base. Takecallis arundinariae siphunculi are pale and the cauda is pale or dusky. The body length is 1.7-2.4 mm.

 

The micrograph below shows an alate Takecallis arundinariae, dorsal, in alcohol.

 

The black-spotted bamboo aphid is found on the underside of mature leaves of bamboos, especially Arundinaria and Phyllostachys spp. Takecallis arundinariae originates from the Far East (India, China, Japan etc), but has been introduced to many other parts of the world including much of Europe, Australia and North and South America. Sexual forms have been found in Korea, but reproduction is entirely parthenogenetic over much of the world.

 

Other aphids on same host:

Of approximately 50 aphid species that feed on bamboo worldwide, Blackman & Eastop (1984)  list 12 'widely distributed species'. Of those Baker (2015)  lists just 3 as occurring in Britain: Takecallis arundinariae, Takecallis arundicolens  and Melanaphis bambusae.

Acknowledgements

We have made provisional identifications from high resolution photos of living specimens, along with host plant identity. In the great majority of cases, identifications have been confirmed by microscopic examination of preserved specimens. We have used the keys and species accounts of Blackman & Eastop (1994)  and Blackman & Eastop (2006)  supplemented with Blackman (1974) , Stroyan (1977) , Stroyan (1984) , Blackman & Eastop (1984) , Heie (1980-1995) , Dixon & Thieme (2007)  and Blackman (2010) . We fully acknowledge these authors as the source for the (summarized) taxonomic information we have presented. Any errors in identification or 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).
