Alopecosa hirtipes
Alopecosa hirtipes is an Arctic wolf spider (family Lycosidae) distributed across northern North America and Eurasia. The species has been studied for its reproductive biology, with research documenting correlations between female body size, mass, and clutch characteristics. As a ground-dwelling lycosid, it inhabits tundra and cold-adapted habitats where it exhibits typical wolf spider behaviors including maternal care of egg sacs.
Faxonius immunis
papershell crayfish
Orconectes immunis, commonly known as the papershell crayfish, is a freshwater crayfish native to central North America that has become invasive in parts of Canada. The species has been documented in southwestern Ontario and Lake of the Woods, where it shows preferences for shallow waters with fine substrates and aquatic vegetation. Reproductive studies indicate significant egg mortality during incubation, with females exhibiting size-dependent fecundity. The species has been subject to cellular-level studies of oogenesis, demonstrating intracellular yolk synthesis in oocytes.
Micrommata ligurina
Micrommata ligurina is an accepted huntsman spider species in the family Sparassidae. A field study in Northeast Algeria recorded it along an elevational gradient from 30 to 1,030 m and found that reproductive timing shifted later with increasing elevation. The species is reported across the Mediterranean region into Central Asia, though the detailed range needs confirmation from taxonomic records.
Paraglenea fortunei
Paraglenea fortunei is a longhorn beetle in the family Cerambycidae. Controlled studies have documented details of its egg-laying and laboratory rearing. In one reproductive study, females placed eggs beneath the epidermis of stem wounds, with a mean lifetime total of about 276 eggs. The available focal-species evidence also includes successful larval rearing on artificial diets.
