The genus Achrysocharoides Girault is here reported for the first time from tropical America. Included are ten species, eight newly described: Achrysocharoides asperulus, Achrysocharoides callisetosus, Achrysocharoides cuspidatus, Achrysocharoides foveatus, Achrysocharoides infuscus, Achrysocharoides mediocarinatus, Achrysocharoides purpureus, Achrysocharoides sulcatus, and two already known: A...

Marmara gulosa Guillén & Davis (Lepidoptera: Gracillariidae) is a sporadic pest of citrus and a number of other crops in southern and central California. Coupled gas chromatographic-electroantennogram detection analyses of headspace volatiles collected by solid phase microextraction from virgin female moths revealed at least four related compounds in the extracts that elicited significant anten...

Zoophilous flowers often transmit olfactory signals to attract pollinators. In plants with unisexual flowers, such signals are usually similar between the sexes because attraction of the same animal to both male and female flowers is essential for conspecific pollen transfer. Here, we present a remarkable example of sexual dimorphism in floral signal observed in reproductively highly specialize...

1. The abundance, survival, and causes of mortality of Cameraria hamadryadella (Clemens) (Lepidoptera: Gracillariidae) were examined on four host plant species in Virginia, U.S.A. Quercus alba L. and Q.rubra L. are native within the geographic range of C. hamadryadella, and Q. robur L. and Q. benderi Baenitz are exotic. Q.robur is native to Europe, North Africa, and Asia and was probably introd...

Choreborogas species are endoparasitoids of leafmining larvae of the Lepidoptera Lyonetiidae and Gracillariidae; the mummified host larva or prepupa is used as shelter during pupation. Emergence is from near the head end of the host (Whitfield, 1990). After Achterberg (1995) the genus can be characterised by malar suture distinct (Figures 1, 2); costulae of propodeum absent or short (Figures 3,...

Four new Epicephala species that feed on the seeds of Glochidionsphaerogynum (Phyllanthaceae) from Yinggeling Mountain Nature Reserves in Hainan Province of China are described: Epicephaladomina sp. n., Epicephalaimpolliniferens sp. n., Epicephalaangustisaccula sp. n. and Epicephalacamurella sp. n. The latter two species are also associated with Glochidionwrightii. Photographs of adults and gen...
