Remarks on the genusSeveriniaFinot 1902 and a description of two new genera of Oxyothespinae (Insecta Mantodea)

A resolution of the confusion surrounding the genus Severinia Finot 1902 is proposed. It is suggested that the males, presently attributed to Severinia lemoroi (Finot 1902), be transferred to the new genus, Paraseverinia, and that the genus Amblythespis Chopard 1943 be considered a synonym of Severinia. In addition, a description is provided of a new genus Somalithespis (Oxyothespini), characterised by the presence of a pre-apical lobe on the mid femurs, a character found for the first time among the tribe of Oxyothespini.

Abundant Prey Can Alleviate Previous Adverse Effects on Growth of Juvenile Praying Mantids (Orthoptera: Mantidae)

First- and second-instar mantids given small amounts of food (similar to prey availability in the field) attained a smaller size and spent more time in those developmental stages than mantids offered as much as they could eat. In two of three cohorts, mantids reared during the first stadium on a low quantity diet recovered during the second stadium when they were switched to a high diet, by having a higher relative consumption rate, gaining as much weight as and spending less time in the second stadium than those reared on the high diet throughout. Consequently, in two of three mantid cohorts, mantids switched from low to high quantity diets weighed as much at the end of the test as those reared continuously on the high quantity diet. When deprived of food just after emergence in another experiment, relative growth rate of mantids given a low diet over the first stadium was unimpaired until the third day without food. In contrast, mantids deprived of food for 2 d and then given a high diet had a high relative consumption rate and the highest relative growth rate, a consequence of fewer days spent in the first stadium. In a third experiment in which three treatments consisted of the same total number of prey per day but presented in different sequences and thus having different prey densities, prey density affected consumption of flies and consumption by mantids was high when prey density was high. However, relative growth rate was similar among treatments, which may reflect distracted mantids at high prey densities. These results show that mantids can compensate under some conditions for short-term food deprivation and effects of local prey density by increased consumption rate, and thus can develop more quickly.

Blue, red, and yellow insects

Notes are given on yellow, blue, and red examples of 7 species of normally green insects in New Zealand. These records include the orders: Mantodea, Plecoptera, Orthoptera, Hemiptera, and Lepidoptera. Results of a breeding experiment with a yellow praying mantis, Orthodera ministralis (Fabricius), are discussed.

Prey Recognition in the Praying Mantis 1)

PREY RECOGNITION IN THE PRAYING MANTIS 1) by SUSAN RILLING, H. MITTELSTAEDT 2) and K. D. ROEDER (Department of Biology, Tufts University-, Medford; Massachusetts, U.S.A.) (With I Plate and 9 Figures) (Rec. 30-III-1958) INTRODUCTION This investigation attempts to elucidate the external factors that release and control prey capture in the praying mantis. Only a few observations on prey recognition in insects are available in the earlier literature (TIRAI_A 1923, BALDUS, 1926), and the more complete recent studies of releasing me- chanisms in insects (e.g. TINBERGEN et C1L. 1942, MAGNUS 1953, BUCHHOLZ 1956) are mainly concerned with recognition of the sexual
