How do trapdoor spiders catch their prey




















When a male locates the burrow of a female, he nods her before entering by tapping on the lid with his font legs. The mating takes place inside the burrow after which the male leaves.

The females cover the lid before laying — eggs in a silken sac.

By contrast, Hammock Web spiders sit on the rock or wood substrate shielded by their hammock-like sheet web. These webs are effective for capturing walking and jumping prey but will also entangle flying prey like moths and flies.

Insects provide the vast majority of spiders' food and many web-based prey catching strategies evolved in response to this plentitude. These included 'space webs', 3-D webs with a maze of threads that delay the prey long enough for the spider to enswathe it in silk or bite it; knockdown webs combining a maze of lines above with a silk sheet below - the maze of 'knockdown' threads stop flying or jumping prey which fall onto the sheet below and also help keep the sheet clear of debris; orb webs, with large, planar catching surfaces that are sticky, strong and stretchy and virtually invisible to flying insects; sticky 'gum-footed' webs like that of the Redback Spider that catch walking prey; and many others.

Many of these web builders use silk enswathing and wrapping to subdue and 'package' their meal for immediate or later consumption. Despite its great success as an insect trap, the orb web has undergone some interesting specialisations. For example, moths are a very abundant food source.

The body and wings of moths are covered in scale-like hairs that can be easily shed, and this often allows them to struggle free of a silk trap. However, some orb web weavers have evolved long, ladder-like orb webs. In such elongate webs, moths lose so many scale hairs while struggling to get free that they become stuck before they can roll out of the web.

Even more specialised prey capture strategies have evolved in other descendants of orb weaver lineages. These involve simplification and modification of the orb web and highly specialised web handling behaviour. There are many other araneomorph spiders that no longer build snare webs. Such spiders also have a surprising range of prey catching strategies.

Many are ambush hunters like the flower or crab spiders Thomisidae. These spiders have quite good eyesight. They sit in the open, on foliage Sidymella spp. Their body colours usually merge well with their background flower frequenting species are capable of adjusting their body colour to suit , concealing them from both predators and prey. Using sight, vibration and touch senses they target insects and other prey alighting or walking nearby - like flies, butterflies and bees, some of which may be considerably larger than the spider.

Their strong, spiny front legs allow them to grasp and hold the prey while it is bitten. A tropical Thomisid species, Phrynarachne decipiens , has gone about things a little differently. Its body colour and shape resembles a drop of bird dung. However, as well as looking like a 'turd' the spider also secretes a chemical scent that makes it smell like one!

The average life span of a trap door spider is 5 to 20 years. Compared to house spiders whose average lifespan is 1 to 2 years. Their venom is non-fatal to humans, however, if bitten it is very painful. Their fangs are larger than other species of spiders, so this makes their bite more painful.

They are known to be aggressive spiders, however, if left alone they will not chase you. Do you have very large spiders around your home? Contact us today and get a Free Inspection from U.
