LACTRODECTUS Meaning and
Definition
-
Lactrodectus refers to a genus of venomous spiders that belong to the family Theridiidae, commonly known as widow spiders. The word "lactrodectus" originates from Latin, with "lac" meaning "milk" and "trodektos" meaning "biter." This is an apt descriptor for these spiders as they possess potent venom and are known for their ability to inject it through their bites.
Widow spiders of the Lactrodectus genus are characterized by their dark-colored bodies, usually black or brown, with distinctive patterns of red, orange, or white on their abdomens. These spiders have the characteristic hourglass shape on their underside, which is a recognized feature of widow spiders. Their size varies, but they are typically small to medium-sized spiders.
Lactrodectus spiders are widely distributed across the globe, found in various habitats such as forests, grasslands, and urban areas. They are nocturnal creatures, primarily active during the night. Lactrodectus bites typically occur when these spiders feel threatened, as a defensive mechanism.
The venom of lactrodectus spiders contains neurotoxins that target the nervous system of their prey, mainly insects. While the bites of these spiders can cause severe pain in humans, they are rarely life-threatening. However, in some cases, individuals may experience systemic symptoms, such as muscle pain, nausea, sweating, and difficulty breathing. Immediate medical attention is recommended for those who have been bitten by a widow spider to receive appropriate treatment.
In conclusion, lactrodectus is a genus of venomous spiders, commonly referred to as widow spiders, known for their potent neurotoxic venom and distinctive markings.
Etymology of LACTRODECTUS
The word "Lactrodectus" has a Greek etymology. It is derived from the combination of two Greek words:
1. "Lactro" (Λάκτρο) comes from the Greek word "lakhtron" (Λάχτρον), which means "a trap" or "a snare".
2. "Dectus" (Δεκτός) originates from the Greek word "dektoς" (Δεκτός), meaning "accepted" or "received".
So, when combined, "Lactrodectus" roughly translates to "the one accepted by the trap" or "the one caught in the snare". This name is attributed to the genus of spiders commonly known as widow spiders, including the infamous Black Widow spider (scientific name: Latrodectus variolus).
