Oriental hornets, Vespa orientalis, are dangerous enemy to bee colonies in some countries of the world. There are more than one subspecies of V. orientalis. Few studies have investigated the morphological characteristics of these subspecies. Morphological characterization can help in confirming and discriminating between the subspecies, and to follow any changes in their morphology over time. In this study, some body characteristics of V. orientalis orientalis queens from Egypt were measured including head width, fore wing length and width, hind wing length and width, femur length, tibia length and approximate stinger length. Also, fore wing characteristics using wing coordinates for 20 landmarks were studied. Computer based techniques were applied to take these measurements. The data of the current study can be utilized for comparisons with other subspecies.

The assumption that the number of eggs laid by a spruce budworm moth in the field is the same as the number laid under laboratory conditions is shown to be false. A method is described for estimating what proportion of the potential fecundity obtained in the laboratory is actually laid in the field. The proportion was shown to range from 0 to 1 for individual females, but averaged between 0.70 and 0.86 for a given population at one locality. Results of this investigation have implications in population dynamics studies of the spruce budworm.

Two Aulacidae from Asia, Pristaulacus japonicus Turrisi & Watanabe, sp.n. (Japan) and Pristaulacus takakuwai Turrisi & Watanabe, sp.n. (Thailand), are described and illustrated. The former species is very similar to the Palearctic Pristaulacus gibbator (Thunberg 1822) and is recognized by the different sculpturing of the upper part of the mesoand metapleura, slightly longer petiole, longer ovipositor, and several features of the male genital capsule, e.g., the shape of the apex of the paramere, lamina volsellaris and penis valve. The latter species is not obviously allied to any other described Oriental Pristaulacus and is recognized by the combination of the following characters: colour pattern, with setae of the body golden, wings yellowish hyaline, fore wing with a moderately wide substigmal brown spot and apex infuscated, hind leg mostly black to black-brown, shape of the head, with temple well developed, and ovipositor relatively short, 0.9× fore wing length. Images of both treated species are freely available at the web site: http://morphbank.net.

Two Aulacidae, Aulacus uchidai Turrisi & Konishi, sp. n. and Pristaulacus superbus Turrisi & Konishi, sp. n., are described and illustrated from females recently collected in Japan. Aulacus uchidai is recognizable among the other Palaearctic Aulacus by the colour pattern, with the metasoma entirely blackish, the weak and not extensive sculpture on upper frons, weakly rugulose-foveolate, the shape of mesosoma with propodeum declivous, the moderately long and slender apical lobe of hind coxa and the ovipositor length, 0.6–0.9× fore wing length. Pristaulacus superbus is a large species (length: 15.3–17.3 mm) with a long ovipositor (1.5× fore wing length), readily distinguishable from other Palaearctic Pristaulacus by the blue to dull green metallic hue on head and mesosoma, the entirely black metasoma and one tooth-like process on each side of hind surface of propodeum. Including the two new species, the number of Japanese Aulacidae is now nine, two species of Aulacus and seven species of Pristaulacus. Images of both species are freely available at the web site: http:/ /morphbank.net. A revised key for the identification of the Japanese Aulacidae is provided.

Wing lengths of Clamorous Reed Warblers Acrocephalus stentoreus in Israel Wing length measurements taken from first-year, pre- and post-moulting (annual, complete) Clamorous Reed Warblers were recorded at a site in northern Israel. The resulting data set was examined using a time-series of residuals (CUSUM). Results from this analysis can explain the reported heterogeneity found in a comparable data set by Merom et al. (1999). Further observations made in their paper are rebutted: (1) an implied assumption that Reed Warbler (Acrocephalus scirpaceus) spring migration in Israel ends by 1 May is contrary to other publications; (2) the late autumn occurence in N Israel of longer-winged 1st cal. yr. Reed Warblers, unconvincingly explained as either delayed migration by larger individuals or post fledging feather growth, is most likely due to birds from different provenances origins moving at different seasons; (3) growth during adulthood in Reed Warbler is not a new discovery, though presented as such.
