• Nesticodes rufipes

  Red House Spider

  Nesticodes rufipes, commonly known as the Red House Spider, is a cobweb spider in the family Theridiidae and the sole species in its genus. It has been introduced globally and is found on multiple continents including North America, South America, and oceanic islands. The species has been studied extensively for its predatory behavior, exhibiting a type II functional response to prey density. Research indicates that habitat complexity significantly affects its predation efficiency, with reduced capture rates in more complex environments due to prey refuge availability.

• Tenthredo grandis

  Tenthredo grandis is a sawfly species in the family Tenthredinidae. Unlike typical wasps, sawflies lack a narrow "wasp waist," with the abdomen broadly attached to the thorax. The larvae are herbivorous rather than carnivorous, feeding on turtlehead plants (Chelone spp.) during midsummer. Adults are often observed on flowers and consume smaller insects as well as pollen and nectar. The species exhibits mimicry of stinging wasps despite females lacking a functional stinger.
