Zoologischer Anzeiger, 2011 Abstract Males of some subgroups of Belostomatidae brood the eggs attached to their backs, whereas the eggs are attached to the vegetation by females in others. Male brood care is obligatory in the belostomatine species of Abedus Stal, 1862, Belostoma Latreille, 1807, Diplonychus Laporte, 1833, Hydrocyrius Spinola, 1850, and Limnogeton Mayr, 1853 ...

Revision of the Belostoma triangulum group (Insecta: Heteroptera: Belostomatidae)
Zootaxa, 2021The genus Belostoma comprises about 70 species classified in sixteen species groups. Here, the remarkable Belostoma triangulum group sensu Lauck, 1964, is revised. Belostoma bicavum Lauck, 1964 is proposed as a junior synonym of B. bachmanni De Carlo, 1957, which is added to this group.

The Higher Classification of the Belostomatidae (Hemiptera)
Annals of the Entomological Society of America, 1961The seven genera recognized in the Belostomatidae pertain to three new subfamilies: LETHOCERINAE, with the one genus Lethocerus; HORVATHINIINAE , with the single genus Horvathinia ; and BELOSTOMATINAE, with the five genera Limnogeton, Hydrocyrius (= Poissonia , = Diplonychus auctt.

The biology of Sphaerodema urinator Duf. (Hemiptera, Belostomatidae)
Zeitschrift für Angewandte Entomologie, 1978AbstractSphaerodema urinator Duf. inhabits water ponds and rice fields in Egypt where it feeds on soft‐bodied animals that haunt these habitats, especially mosquito larvae and pupae. The seasonal cycle of S. urinator is passed by three annual generations, and consists of an active period (May—November) and a sexual quiescent period (November—May).Eggs ...

The Locomotion of Lethocerus (Hemiptera, Belostomatidae)
Annals of the Entomological Society of America, 1959The external and internal skeleton and the musculature of the pterothorax of Lethocerus are described and figured. Studies of these structures revealed that the front and hind wings possess definite mechanisms for eoaptation, and that torsion of the wings is regulated by modified external sclerites rather than by the musculature of the basalare and ...

The salivary gland and salivary enzymes of the giant waterbugs (Heteroptera; Belostomatidae)
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2006The giant waterbugs are predators that utilize extra-oral digestion and are known to capture a wide variety of prey. Herein we describe the differences in salivary enzyme composition between large and small species of giant waterbug (Lethocerus uhleri, Lethocerinae and Belostoma lutarium, Belostomatinae, respectively). The saliva of L.

The Salivary Pumping Apparatus of Belostomatidae (Heteroptera)
The Canadian Entomologist, 1964The heteropteran cephalic endoskeleton is difficult to study in dissections, due to its small size and to the delicacy of many of its membranous components. These difficulties are less of a handicap in dissections of the giant water bug Lethocerus (Belostomatidae), and it is possible to observe, in this insect, details of the salivary pumping apparatus

Muscle Regression in Belostomatid Bugs (Heteroptera: Belostomatidae)
Aquatic Insects, 2001Differential flight muscle regression was registered in Belostoma elegans (Mayr, 1871) and B. oxyurum (Dufour, 1863). A two year survey in contrasting habitats showed the preference for the more stable ones by B. oxyurum, and the more unstable ones by B. elegans. Fibrillar muscles were regressed in most of the B.
