The Arrow-shaped micrathena spider has a unique arrow-shaped tummy, which is why it’s named that way! This spider is part of the orb-weaver family and lives mainly in the eastern United States and Central America. This post will share cool facts about this interesting spider.
The eggs are small and round, laid on the sides of the web, near a leaf. They remain in the sac for the winter and hatch the following spring.
After hatching from the eggs, the spiderlings initially have longer abdomens and shorter spines. As the spiders mature, they acquire an adult-like body pattern.
The male and female species spin spiral webs positioned vertically in an up-down posture. Most of the webs also have a zig-zag decorative structure called stabilimentum, a little above the middle portion. Like most other orb-weavers, they too rebuild the webs regularly.
Yes, Arrow-shaped Micrathena spiders have venom. They use it mostly to catch their food.
Yes, they can bite, but it’s rare for them to bite humans. If they do, it’s usually not serious and just causes a little discomfort.
Arrow-shaped micrathena spiders are diligent predators in their ecosystems. By consuming a wide range of insects, they help control pest populations, contributing to the ecological balance within their habitats. These spiders demonstrate daily industriousness by rebuilding their webs, ensuring maximum efficiency for capturing prey.
Natural Predators: Birds and larger insects are the main predators of the Arrow-shaped micrathena. The spiders’ spines and vibrant colors may serve as deterrents, but they are not foolproof against all threats.
Prey-Predator Dynamics: Their diet mainly consists of insects that become ensnared in their sticky webs. The stabilimentum in their web may play a role in capturing prey or even deterring predators by making the web more visible and therefore avoided by larger animals that could destroy it.
Relationship with Humans: Arrow-shaped micrathena spiders are typically harmless to humans. Their presence is actually beneficial as they help in reducing the population of insects that could be pests to human activities. Their bites are rare and generally only result in minor irritation. However, due to their distinctive appearance, they are often noticed and appreciated by nature enthusiasts.
