Most recent animal discovered1/2/2024 “Because this was during COVID, I took some of them back home and put them in the microscope and took pictures with my phone.”īrandão said, “the N. Vinson both cataloged and collected samples of wasps that emerged from the catkins and did the observation experiment where we’d put the bugs into a petri dish with a bunch of tissues and then watch to see where they go.” “We would go out together and collect the catkin galls and tissues for the behavioral tests in Petri dishes, but she had to go every day to the lab to see if any bugs had emerged. Valhalla that had just emerged from catkin crypts at Rice and catch them in the act of laying their eggs into a different part of the plant.” Valhalla.īrandão said, “To confirm where they were going after they left the flowers, I performed an experiment where we offered the wasps a bunch of different tissues from the tree and observed them. Further analysis revealed that the unknown wasps were the lost generation of N. They found that these Florida live oak species differed from the Rice trees where N. Scientists sampled the galls from a Florida live oak species. Finding out where the insects went in their alternate generation took both luck and hard work. Genomic testing combined with detailed observations in nature was crucial for determining N. So they have to lay eggs on different tissue.”Įgan said alternating generations of gallers have often been mistaken for new species in the past. But the flowers are a one-time thing each year, and by the time they appear, there are no more flowers for them to lay eggs on. They develop in galls on the flowers, and then they emerge. Valhalla lays their eggs into the catkins that are developing. Valhalla laid its eggs in its alternating generation took a bit of time. Valhalla - like many other galleries - lays eggs two times a year. It took almost four years to describe the new species because N. Their only purpose is to mate and lay eggs.” Some emerge from spherical brown galls that form on the underside of oak leaves, whereas others form galls inside branches and others on the trees’ flowers.īrandão said, “Once they emerge, they only live three or four days. There are almost 1,000 known species of gall wasps. Valhalla tricks their host tree into feeding and sheltering their young. Armed with some patience and a magnifying glass, the discoveries are endless.” In my lab, undergraduate and graduate students share in the experiential learning process by studying biologically diverse ecosystems on the live oaks right outside our front door. Biologist Scott Egan said, “At Rice, we emphasize learning by doing.
