Hosts. Neuroptera : Chrysopidae , Hemerobiidae

iceryae Howard 1887: 488 View in CoL

Type. USNM

Distribution. W (Alameda, Contra Costa, Los Angeles, Marin, Napa, Orange, Riverside, San Bernardino, San Diego, San Luis Obispo, Santa Clara, Sonoma, Ventura)

Host/habitat. Ceraeochrysa cubana , C . lateralis, C . sanchezi, C. valida , Chrysoperla ploribunda , C. rufilabris , Leucochrysa floridana , Sympherobius angustus , Sympherobius californicus ; NEW: Chrysopa nigricornis (EMEC)

Remarks. Icerya purchasi and Saissetia oleae were erroneously reported as hosts by several authors—these reports are attributable to parasitized Chrysopa larvae, which pupated within the hollow shell of a dead scale ( Clancy 1946a). Similarly, I consider the host report of Coccus hesperidum ( De Santis & Monetti 2008) to be in error. Clancy (1946a) also questioned the validity of hemerobiid host records, but noted that I. iceryae would reproduce on Eremochrysa punctinervis in the lab. A series of specimens was reared from galls of Heteroecus dasydactyli (Ashmead) ( Hymenoptera : Cynipidae ) in San Bernardino County (UCRC). Harrisina brillans ( Lepidoptera : Zygaenidae ) is noted as the host for one specimen (UCRC), but this is undoubtedly erroneous.

Type. USNM

Distribution. W (Alameda, Los Angeles, Santa Clara, Solano, Ventura)

Host/habitat. Chrysopa nigricornis , C . oculata, C . pallens, C. sp., Chrysoperla carnea , Sympherobius angustus , Hemerobiidae sp.

Remarks. Clancy (1946a) considered the only valid host records for this species were for the two closely related species, Chrysopa nigricorns (= C. majuscula ) and C. oculata . Host records for Chilocorus similis and Lymantria dispar (Linnaeus) are clearly erroneous, while records for “ Chrysopa ” may equally refer to Chrysoperla .

spp.

Remarks. A specimen determined as “sp. nr. axillaris ” ( Timberlake 1919c), was recorded from Chrysopa nigricornis in Contra Costa County (EMEC), and what appear to be undescribed species near atriventris ( Ashmead 1900) were collected on aphid-infested Pinus sabiniana in Calaveras County and Liriodendron tulipifera (Magnoliaceae) in Stanislaus County (both RLZC).
