Bugs can be found on all three species of golden rain trees, but the most common tree on the UCD campus is 'Koelreuteria paniculata. You can see a tree with bugs living beneath it on the south side of Wellman Hall. The tree is in a concrete pot at ground level near the bike racks. it is to the right if you face the below ground entrance to Wellman. The bugs you will be looking at in lab were collected from local golden rain trees. For these insects, the balloon vine is the introduced food source Q13 picture the morphology of an average soapberry bug from a rain tree population and compare it to the morphology of its new food source, balloon vine seeds. This average bug was taken from a population containing a range of sizes. Are large, small or average bugs more likely to have relative fitness on the new food source? Large Small O Average Q14a List one change in bug morpholog been living on golden rain trees. ect in bug populations that have Your answer Q14b List one change in behavior that you would reasonably expect in bug populations that have been living on golden rain trees. Your answer

Explanation / Answer

13) Small bugs would have more relative fitness on the new food source. As, the size decreases, more is the probablity or the chances of being relatively fit on the new food source. This can also have another dimension; they won't be easily spotted by predators adding to their greater stability and fitness. Also, they would be also able to move faster.

14) The change which I would expect in bug morphology and behaviour which had been living on the golden rain trees is that as they would become smaller in size, they would be able to reach their food faster, there would be lesser competetion because food sources would be abundant comparatively to their requirements and they would be able to climb relatively more easir on the trees. Decrease in the competetion would lead to a decreased urge of reproduction.
