The brown widow is lighter, has an orange or yellow hourglass, and has a black and white pattern on top of the abdomen that the black widow does not have. In southern Africa, the brown widow's relative L. rhodesiensis, native to Zimbabwe, is also called a brown button spider.1

Like all widow spiders, the brown widow has a neurotoxic venom, which attacks the nerves. It causes latrodectism, a set of very unpleasant symptoms. The effects are usually confined to the bite area and the tissue around it.1

Odamlar uchun qanchalik xavfli?

Odamlar uchun xavf: OgʻriqliJuda ogʻritishi mumkin, lekin deyarli hech qachon jiddiy emas.

Brown widow bites are usually not very dangerous, and are much less dangerous than black widow bites. The spider cannot deliver as much venom as a black widow, so its bites are considered minor. They are painful.1

Faktlar

In Southern California, researchers suggest the brown widow may be pushing black widows out of the area by competing and fighting for territory.1

Its egg sacs are so spiky that they are easy to tell apart from those of most other spiders.1

A female can make up to 20 egg sacs over her lifetime, with 120 to 150 eggs in each.1

Brown widows are preyed upon by wasps, including blue mud-dauber wasps and digger wasps.1

Afsonalarni fosh qiluvchi
