Gypsoaphis oestlundi

Woolly honeysuckle aphid

Identification & Distribution

Adult apterae of Gypsoaphis oestlundi are green and quite thickly covered with white wax (see first picture below). Antennal segments I-V are very pale, but segment VI is darker. The legs are also mainly pale. There are no dark markings on the dorsal abdomen, but it does have a full set of marginal tubercles. The siphunculi are as pores with partly sclerotized rims. The cauda is semicircular, much shorter than its basal width in dorsal view. The body length of adult Gypsoaphis oestlundi apterae is 1.5-3.3 mm. Immatures are coloured as the adults and covered with white wax.

Alatae (see picture below) are also green. They have secondary secondary rhinaria on antennal segments III and IV.

The woolly honeysuckle aphid feeds on terminal young shoots and leaves of a few species of honeysuckle (Lonicera). The life cycle of the species is unknown. Hottes (1952) recorded Gypsoaphis oestlundi feeding on Lonicera from several locations in Illinois state, USA in the months of May and June. The species is found throughout much of North America.

Acknowledgements

We are especially grateful to Claude Pilon for pictures of Gypsoaphis oestlundi (for more of her excellent pictures see).

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 Palmer (1952), Hottes & Frison (1931) & Footit & Maw (1997) as well as Blackman & Eastop (1994) and Blackman & Eastop (2006). 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).
