アリジゴクの巣穴掘りと獲物の引きずり込み Antlion Digging Trap & Dragging Prey

左の個体は穴掘り中。反時計回りに後退しながら大顎で砂粒を外に跳ね飛ばす。回る向きは決まっているのだろうか？※　体の構造が非対称？
右の個体は捕食中の蟻を咥えたまま後退して地中に潜り込んだ。暴れる蟻を引きずり込んで生き埋めにすることもある（次の動画を参照）。
※追記：アリジゴクの回る向きは常に同じではないそうです。（参考図書『砂の魔術師アリジゴク：進化する捕食行動』中公新書←おすすめ！）
Antlion on the left constructing a conical pitfall by flicking sands off with its jaws, crawling backward anticlockwise. The right one, on the other hand, dragging subdued prey underground. Video captured by webcam on early-June, 2007 in Japan. The plastic bottle was 8cm in diameter.

Antlions are my all time favorites coz you don't have to go to other planets just to look for aliens. Its all there:-)

[sigma1920]

can't agree more.

what a cool ambush predator the antlion is!

i wonder if the spiral direction of their digging is always the same (clockwise or counterclockwise).

we can find their nests on the dry ground under the floor here in jpn.

i am curious to know what sort of habitat the tropical antlion lives in ur country (phillippines)?

We have a lot of antlions back in my home town province back in Leyte (Visayan Islands). They are more spotted in in coloration and a I think its the same size just like yours in ur country Japan. You can find them close to beaches under cottages, and nipa huts with a lot of shade from the sun. Dude, you should the "Madagascan Giant Antlion" These guys are about an inch long and are known to be the wolds larges antlions!

Haha, one at the right is like "Stop kicking sand into my hole!"

Closest insect we get to these is the green lacewing's larvae. Their bite itches.

i have read that the antlion injects venom to paralyze its prey.
