Mr. David Landes - amateur naturalist Recent studies in entomology, arachnology, arthropod paleontology, & speleology. Many of these studies may reveal a sort of evolutionary/ecological twist. A., J.

Focuses on recent studies in entomology (mostly Hymenopterans) and arachnology, sometimes accompanied with articles from various scientific journals. Briefly included are publications and literature citations from my own past research. Also provided are numerous newsfeeds covering phenomena from other areas of interest in the natural sciences, e.g., my newly acquired interests in paleontology and

speleology.~

Extremely well-preserved fossil sawfly sheds new light on co-evolution of insects and toxic plants

Despite the name, sawflies are not flies but a type of wasp, with spitfires the most widely recognised group of sawfly species in Australia. They are called sawflies because they have a saw-like ovipositor that is used to lay eggs, and they could be mistaken as flies because they lack a typical ‘wasp waist’.
