Reproduction and Lifespan

Mating Patterns

The Green Orbweaver, like other spider species, has a unique mating pattern. Males and females have distinct roles:

  • Males: They court female orb weavers by plucking the female’s web and exhibiting specific body movements.
  • Females: If receptive, they respond to the male’s advances and allow the male to mate.

Egg-Laying

Female Green Orbweavers lay their eggs in a protective silk sac after mating. Some key points include:

  • Females can produce multiple egg sacs.
  • Each sac contains hundreds of eggs.
  • Egg sacs are strategically placed in sheltered areas to protect them from predators and harsh weather conditions.

Lifespan

The lifespan of Green Orbweavers can vary, but some general observations are:

  • Males: Typically shorter lifespan, often dying soon after mating.
  • Female orb weavers: Live longer, allowing them to lay eggs and rear offspring.
  • Overall: Green Orbweavers usually live for one season, with new generations emerging annually.

Molting

Molting is an essential part of the Green Orbweaver’s life cycle. Here’s what you should know:

  • Molting allows growth and development of the spider.
  • Both male and female orb-weavers undergo several molts throughout their life.
  • The process includes shedding the old exoskeleton and growing a new one.

Orbweaver’s Impact on Human Life

Beneficial Effects on Gardens and Parks

Green Orbweaver spiders have a positive impact on gardens and parks due to their role in maintaining a balanced ecosystem. They contribute to:

  • Natural pest control: Orbweavers help reduce the population of harmful insects that can damage plants and vegetation.

Dear Katja,
The best we can do at this time is to provide a general family name.  This is a harmless Orbweaver in the family Araneidae.

Thank you Daniel,
They will be happy to hear it is harmless, since they turned it loose in their yard! Any further information would be appreciated…it really is a cool looking spider,

Hey bugman,
A friend of mine found this spider on a curb this morning in Rome.
I did some digging, and think it might be the Misumena Vatia. However, I am not sure. The pictures I was able to find online are not 100% identical to the spider in the picture.
Any idea?
Thanks!

Hi Saverio,
This is most definitely not a Crab Spider.  It is an Orbweaver in the family Araneidae, possibly
Araniella cucurbitina, a green species found in the UK and parts of Europe and pictured on UK Safari.

Thanks Daniel. Very helpful
