Jack Schultz @jcschultz.bsky.social · 07/11/2025t's raining galls! Galls of the mealy gall wasp are falling out of the southern live oaks all over Houston. As you can see, a lot of them are damaged, as though something tried to eat the larva in the center chamber. 010
Jack Schultz @jcschultz.bsky.social · 29/07/2025Phasmidae - stick insects -often produce highly-figure eggs that appear to have erils. They don't have erells, but some experts think that some phasmid eggs may escape predators this way. Eggs are widely scattered, perhaps to evade predators. 010

Jack Schultz @jcschultz.bsky.social · 19/02/2025The lumps on this #leaf are #domatia, cavities that house (usually) #mites. The mites prey on harmful mites or clear fungi. Domatia may be induced by the mites or are part of the plant's development. I think these are the latter. Plant species unknown, from Peru. 000

Jack Schultz @jcschultz.bsky.social · 12/02/2025It’s #Darwin Day. He was interested in the #galls #insects induce on #plants. He mused that gall development is caused by injected insect chemicals altering the plant’s own signals and that this involves fruit development traits, resulting in galls that resemble fruits.
