Discovering spiders
Unraveling the world of spiders
Spiders, classified as Arachnida in the order Araneae, are commonly found as household pests. With around 50,000 species worldwide, their often-harmless nature is overshadowed by an appearance that triggers fear and even phobias.
They come in many sizes, shapes and colours, and often reside in corners, ceilings, basements, windows and under furniture. Some species are venomous, but not all pose a threat to humans.
Venom is used for self-defence and to help digest prey. In rare cases, certain species may cause discomfort or other health issues, which is why timely identification and control matter.
Biology
Life Cycle of Spiders
From eggs in a silken sac to spiderlings that molt into independent adults weaving webs for prey.
Egg Sac
The sac shields eggs from predators. Females may carry it or attach it under leaves and in concealed spots.
Spiderlings
Young spiders resemble miniature adults and undergo several molts as they develop.
Adult Stage
After multiple molts they become fully independent adults and begin solitary lives, weaving webs and capturing prey.
