Wasps Favor Large Size for Sex

Size matters when it comes to sex. When in the orchid world it does anyway! The plants rely on wasps for fertilization. Apparently, male wasps are attracted to the largest orchids. Shape of plants also has a role. Orchids are a replica of female wasps, in shape and scent. Two orchids who had two kinds of wasps enamored with them were observed. The wasps did visited both types of plants but they spent more time "copulating' with their favored orchid. Scent is offered to male wasps on little black beads. This only attracts males to the flowers. Once there, shape and size of blooms affects whether wasps stay or go. Orchids also benefits from this because plants with larger flowers are fertilized and they produce the next generation of orchids. ◆ Chemistry by Ty Buchanan   ◆ Adventure Australia Funny Animal Photos Funny Weird Things Articles News Reviews ● Vista Computer Solutions Blog                Australian Blog   ★   Adventure Austral

Solution to Bee Die-Off?

It is not widely known just how important bees are to maintain our food output, let alone to increase it as demand strengthens. There are so many mysteries to why bees are dying off across the world. Many theories are put forward. Unfortunately, there are few answers to the problem. We need to look after the human friendly insect. It could eventually be found that bees are being killed off by chemicals. However, like other animals bees need chemicals to treat illnesses. When they become infected they change their foraging habits seeking pollen from plants that store certain chemicals. The solution to bee die-off could lie in studying this phenomenon. Plants synthesize chemicals that attract select species of pollinators. Other substance also deter potential attackers. Herbivores have been real pests to plants for millions of years. Eating the leaves can kill plants. Insects have evolved to go where plant toxins drive herbivores away. All nectar is not the same

Caterpillars Are Changing into Butterflies Earler

Climate change is making butterflies more active. They are coming out 10 days earlier than they used to in spring. The change has been caused by a 0.91ºC increase in temperature in Melbourne. All species that interrelate with the Common Brown butterfly ( Heteronymph Merope ) breed earlier as well. A group of academics funded by the Australian Research Council has researched this issue. Members of the group studied caterpillars bred at the old and new temperature in the laboratory and noted the change. Observation of the butterfly in the wild has confirmed that caterpillars are changing into butterflies earlier. If butterflies are coming out sooner then other insects must be doing so as well. This means that crops will have to be planted earlier to be fertilized by insects. Bees are not the only insects needed to grow crops.  People in cities do not understand the importance of pollination on food crops. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.bl
