[11][14][23] Katip can catch insects much larger than themselves. However, a male katip cannot mate with the female redback as the male katip is heavier than the male redback, and when it approaches the web it triggers a predatory response in the female leading to the male being eaten before mating occurs. [8], Webs are typically established in low-growing dune plants and other vegetation such as the native pngao (Ficinia spiralis) or the introduced marram grass (Ammophila arenaria). [14] After mating, the male retreats to groom, which is performed by running his palps and legs through his fangs and wiping them over his body. All this ensured that for millions of years there was a natural spider-bird balance in New Zealand. New Zealand certainly has lots of spiders. With all suspected spider bites it is important to know which spider may have been responsible.
