Micro Movements in the Cyrtarachne
2 years ago, I posted some examples of bugs which exhibit micro movements when they appear to be at rest when viewed with the naked eye. It was only much later that I managed to document this movement in the
Bird Dropping Spider (
Cyrtarachne sp.) when I found one and actually remembered to shoot it. 😛

#1 The
Bird Dropping Spider (
Pasilobus sp. Cyrtarachne sp.) with an unidentified fly plastered onto the abdomen

#2 The micro movements. I do not have any verified theories to these movements, but my first thought was that it was due to the movement of digestive juices in the spider. David Court had suggested that it could also be a anti-predator warning device.

#3 A juvenile Huntsman Spider

#4 Unidentified eggs, looked like golden eggs!

#5 Female
Wolf Spider (Lycosidae) carrying an egg sac

#6 Front view of the same wolf spider

#7 A
Jumping Spider (
Siler sp.) captured this planthopper nymph while we were observing it.

#8 It loved to raise it’s 2 fore-legs in this manner. To ward off predators perhaps?

#9 Yes, still doing it. Surrender? lol

#10 Back view. Very colourful abdomen

#11 Top view. We were hoping that this was a peacock spider, but it was not to be. 😛

#12 Relatively large
Crab Spider (
Angaeus rhombifer)

#13 Top view of the crab spider

#14 Unidentified caterpillar, with a very stout body and vibrant colours

#15 Better view of the patterns on it’s body

#16 Close up of the head

#17 A very small
Spitting Spider (
Scytodes sp.)

#18 Leaf-like Katydid

#19 Male Huntsman (
Heteropoda sp.)

#20 Face shot to show the eye arrangement

#21 Cute little ladybird

#22
Tree Stump Orb Weaver (
Poltys elevatus)

#23 Side view of the tree-stump wannabe. The abdomen is thinner than the previous ones that I had shot before:

#24 Managed a portrait shot. This was already focused to infinity with the Raynox 250 slapped on.

#25 Another
Crab Spider (
Angaeus rhombifer)

#26 Front view of the eyes.

#27 This spider caught my eye with the jade-green abdomen. Probably a
Kidney Garden Spider (
Araneus mitificus)

#28 Unidentified fly? Possibly a mirid bug

#29
Wandering Spider (
Ctenus sp.) on the ground, munching on a roach

#30 Found this dead Mantidfly on the way out of the trail. 🙁

wonderful pictures! as for the micro movements …well, i am no expert…but could it be because of some kind of parasite? something like Leucochloridium paradoxum that parasitizes snails?
