The Bolas Spider That Hunts by Lassoing Its Prey

People generally think of spiders as hunting for their prey by building webs.
However, the Bolas spider's hunting technique is quite
extraordinary. It first produces a thread stronger than silk inside
its own body. It then places very powerful and sticky droplets on
the end of this thread. It then dangles the thread from a tree,
rather like a fishing rod, and begins patiently waiting for its
prey. It also employs a miraculous tactic to attract its prey toward
it. It manufactures a scent in its body and then releases it! How?
Female moths release a special scent hormone known as a pheromone
to attract males. Bolas spiders replicate this scent and place it at
the edge of the lure. In addition, they can change this pheromone
to match the features of other insect species. Deceived, the male
moth heads in the direction the scent comes from. When the moth
approaches, the spider places the lasso on its two front feet and
casts it, faster than the human eye can see. The sticky tip flies
through the air and sticks to the moth's body, and the prey is
caught. The adhesive substance sticks to the moth's body and the
insect is reeled in. The fine but very strong thread can easily
carry living things much heavier than itself at its tip. The Bolas
spider wraps the moth up in a special silk it produces. The
distinguishing feature of this silk is that it keeps the food fresh
for a long time. The spider thus keeps its prey fresh to be
consumed at a later time.
Its marvelous plan has worked.
There is another point to bear in mind here.
The Bolas spider is practically blind. Yes, that's right! Spiders'
eyesight is very poor, but they can perceive the vibrations caused
by insects when they fly. Although the Bolas spider is almost blind,
it can catch a flying insect with the help of the lasso it makes
itself hanging suspended in the air. This is an obvious miracle.
Let us now review what the Bolas did in order to hunt, step by step:
-It manufactured a silk thread stronger than steel but highly
flexible, and prepared an adhesive ball right at the end of it...
-It produced a scent manufactured by an insect, from a totally
different species to its own, and released it...
-It threw the lasso at its prey faster than the human eye can see.
-The lasso hit the target even though the spider was suspended in the air.
-Finally, it wrapped its prey up in a special silk to keep it fresh.
Almighty Allah, Lord of the universe and all living things, once
again shows us His sublime and unique creative artistry in this
spider.
The way that every spider ever born knows the hunting techniques
employed by its own species is a miracle all by itself. For example,
this Bolas spider made its first lasso when it was still a baby; at
that time, it is smaller than a fingertip. The lasso is smaller
than a pinhead. But it knows just what it has to do.
There is no doubt that this ability to spin webs and set traps shows
that spiders are "inspired." It is without doubt Almighty Allah,
Lord of all the worlds, Who creates these creatures with these
wondrous characteristics and inspires in them all they do.
I seek refuge in Allah from the accursed satan-
I have put my trust in Allah, my Lord and your Lord. There is no
creature He does not hold by the forelock. My Lord is on a Straight
Path. (Surah Hud, 56)
