Using a Black Light to Collect Insects at Night

Using a Black Light to Collect Insects at Night Entomologists use black lights, or ultraviolet lights, to sample and study nocturnal insects in an area. The black light attracts night-flying insects, including many moths, beetles, and others. Many insects can see ultraviolet light, which has shorter wavelengths than light visible to the human eye. For this reason, a black light will attract different insects than a regular incandescent light. If youve ever seen a bug zapper, one of those lights people hang in their backyards to keep mosquitoes at bay, youve observed how UV light attracts a lot of insects. Unfortunately, black lights do not work well to attract biting insects, and bug zappers harm more beneficial insects than pests. Blacklight sampling can be done one of two ways. The black light can be suspended in front of a white sheet, giving flying insects a surface on which to land. You can then observe the insects on the sheet, and collect any interesting specimens by hand. A black light trap is constructed by suspending a black light over a bucket or other container, usually with a funnel inside. Insects fly to the light, fall down through the funnel into the bucket, and are then trapped inside the container. Blacklight traps sometimes contain a killing agent, but can also be used without one to collect live specimens. When using a black light to collect insects, you should set up your light and sheet or trap just before dusk. Make sure the light faces the area from which you want to attract insects. In other words, if you want to draw insects from a wooded area, position your light between the trees and the sheet. Youll get the greatest diversity of insects if you set up a black light at the intersection of two habitats, such as at the edge of a meadow adjacent to a forest. Use forceps or an insect aspirator (sometimes called a pooter) to collect insects from the sheet or trap.

Anfangen (To Begin) German Verb Conjugations

Anfangen (To Begin) German Verb Conjugations Anfangen is a strong (irregular) verb that means to begin or start. As a strong verb, it doesnt follow a strict rule and you will need to memorize how it is conjugated in its different tenses.   In addition, the verb  anfangen  is a separable prefix verb. That means that its prefix (an-) separates when the verb is conjugated, even in its past participle form (angefangen). There are cases where the prefix does not separate. These include the infinitive form such as with modals in the future tense, in dependent clauses, and in the past participle (with ge-). While a separable prefix may seem confusing, keep in mind that it is like English verbs such as fill in, clear out, etc. The difference is that in English the second word can come either right after the verb or at the end of the sentence. In German, it usually comes only at the end of the sentence. Sample Sentences With the Separable-Prefix Verbanfangen, to begin, start Present Tense Wann  fangen  Sie  an? - When do you begin? Ich  fange  heute  an. - I start today. Present Perfect Tense Wann  haben  sie  angefangen? - When did they begin? Past Perfect Tense Wann  hatten  Sie  angefangen? - When had you begun? Past Tense Wann  fingen  wir  an? - When did we begin? Future Tense Wir werden wieder  anfangen. - We will begin again. With Modals Kà ¶nnen  wir  heute  anfangen? - Can we begin today?
