Maddie Tyson came to me bearing a spec of dust that hurt my eyes to try and focus on. I was quite literally about to brush it off, when it moved... This is the first time that I have encountered the wolf in garbage clothing, that is the larval form of the green lacewing (Chrysopidae).
Well done for finding this super-predator of the micro world Maddie! The reason that this lacewing goes to such length to disguise itself is that it has to avoid the police... in the form of ants, who would keep it from its food source, green aphids. Sometimes the lacewings will glue dead aphids on their backs to avoid the ant patrols that police the aphids to drink their sweet excrement. Yuk! But that's how it works... The aphids suck the plant sap and excrete the sugars that the ants love. The green lacewing larvae try to steal and "aphid sheep" for lunch, and the ants try to keep the lacewing wolves out. What a fascinating world.
A display of all the superb creatures found at Escuela Bella Vista in Maracaibo Venezuela, (and previously where I taught at the American international school of Maputo Mozambique). At least once a week a child brings me some arthropod or other creature to identify, play with or admire. This blog seeks to honor those avid inquirers. Unlike the Lorax who spoke for the trees, Ispeakforthefleas! Enjoy.

Daphnis nerii (The oleander hawk moth) at the 4th grade classroom.
The larvae of this moth feed almost exclusively on the oleander plant and in so doing they pick up a load of neurotoxins that offers protection to the adult. DO NOT have one of these for supper.
